However, sorry for annoyance, but I just meant to add this requested and updated version of 2M 1207 b protoplanet.
I've still to find a way to get clear rocky bodies around the dust rings, but visible debris displayed seems work good, doesn't it?
I hope you like it. Edasich's Work - Page 2 Icon_cat

Well, the person who requested person says that it's a very good work. On the case of the rings, it's better than I expected. The ordered outer rings with lots of dust and the spiral-shape inner ring showing the event with the Neptune-size planet. The planet itself is very good too, with this red glow showing the heat resulting from the collision. So, I congrad you Edasich.

Monday thread bump. Some updates: Edasich's Work - Page 2 Icon_wink


33) - HD 38529's multiplanet system. Planet b, eccentric hot jupiter (I complain about grainy appearance due to image capture)...

Edasich's Work - Page 2 HD38529b


...and Planet c, superjovian planet. With a dense ring of dust and particles.

Edasich's Work - Page 2 HD38529c



34) Gamma Cephei Ab: roughly alike Whathmough's version.

Edasich's Work - Page 2 GammaCepheiAb


35) PSR B1257+12's planetary system, the most famous pulsar planet system. Scaled by size.

Edasich's Work - Page 2 PSRB125712System


36) And then an unconfirmed planetary object: SWEEPS-10. Star is an early M dwarf with an extremely close hot jupiter (1.24 Jupiter radii): 0.008 AUs. To be confirmed.

Edasich's Work - Page 2 SWEEPS-10


Zoomed view.

Because of their young age (nearly 800 million years) and because of strong radiations from homepulsar that continuously stress planet's crust.

Edited. Typos make awful confusion sometimes. Edasich's Work - Page 2 Kopfschuettel

Anyway once Lazarus said these planets might have re-accreted again from previously destroyed planet (If I remember correctly).
Assuming their accretion been quite recent, activity has got to be high.

I think that the PSR 1257+12 planets re-accreted from the debris from after the supernova, instead of a destroyed planet. I'm not entirely sure a supernova has the power to destroy a planet (assuming it's not a close-in planet).

And by the way, your gas planet textures are stunning. Edasich's Work - Page 2 Icon_eek Edasich's Work - Page 2 Icon_biggrin

I plead not guilty there... (though willing to change my mind if you find the URL Edasich's Work - Page 2 Icon_wink ) problem with pre-supernova planets is that the mass loss in a supernova is a very good way of unbinding the system. Likeliest scenario is a supernova fallback disc.

Whether tidal heating would be an issue I don't know... it seems likely that all three planets are in synchronous rotation despite the relatively young age of the system (spindown age ~800 million years) - anyone got any references for a formula for quantifying tidal heating?

Edasich's Work - Page 2 Tidalheating

I don't recall where I got it though.

The heating flux through the planetary surface can simply be expressed as the tidal heating divided amongst the surface area of the planet.
h = H / 4*pi*R_planet^2

Forgive me for thread bumps, but I reckon this couple of pictures really deserve attention:


38) HD 49674 b: eccentric hot neptune in tight orbit.

Edasich's Work - Page 2 HD49674b


39) HAT-P-2 b: eccentric hot super-jovian.

Edasich's Work - Page 2 HAT-P-2


40) HD 43691 b: hot jupiter in eccentric orbit. Here night...

Edasich's Work - Page 2 HD43691b


... and here the day side.

Edasich's Work - Page 2 HD43691bDayside


42) XO-5 b's eternal dawn.

Edasich's Work - Page 2 XO-5bEverdawn


The F5 type sun bakes the dark world for evermore...


43) And finally, since none (except me) can't know anything about this exoplanet candidate yet, I offer "fan service" for you : 30 Arietis Bb. Edasich's Work - Page 2 Icon_lol

Edasich's Work - Page 2 30AriBbcloseup


Edasich's Work - Page 2 30AriBb




I can't anticipate anything, only show you the star is member of a hierarchically triple system (30 Ari Aa-Ab is the bright dot at planet's left) as pointed out back in 2007 (I think) in Santorini Meeting on Extrasolar Planets. If we consider the exoplanet candidate, the system turns out quadruple then. Edasich's Work - Page 2 Icon_rolleyes

Consider I had to generate the stellar system by myself. And Celestia stellar temperatures differs a bit from actual ones and modelling stellar radius and spectral types, planet temperatures aren't sometimes entirely correct.
The planet would be actually hotter and more massive.

Thread bump for GJ 667 C needed. Though I prefer call it "MLO 4 C" as at Solstation. They have also updated related page MLO 4

44) - My model for Gliese 667 Cb, super-Earth in tight orbit.:

I must have done the math wrong, but the planet I put in to Celestia had a much greater separation from the host star. I calculated a value of 0.051 AU, what's yours?

Same, but an error was hiding in the script files...

Unreasonably the M-dwarf showed "1 Solar radius". Edasich's Work - Page 2 Suspect

Gosh! It is not a protostar! Edasich's Work - Page 2 Icon_lol

Fixed, anyway Edasich's Work - Page 2 Icon_wink

And begging your pardon I'm adding Gliese 433.

45) Gliese 433 b, another hot super-earth.

A little thread bump, I was bored Edasich's Work - Page 2 Icon_lol


46) LRc01-E2-4295: topic readers are saying "WTH?". Even if I had typed CoRoT 10101123916, impression would have been the same.
So what is this?

Edasich's Work - Page 2 Corot-7Copycat


According to Planetary transit candidates in CoRoT-LRc01 field it could be a "Corot-7 copycat":

Quote :
This candidate has a low priority because it is faint, and there are marginal indications of a secondary in the light curve. The target star has an mV = 16.5, and a spectral type according to Exo-Dat of M0V. With a period of 1.13828d and a depth of the eclipse of 0.28% (duration 2.9 h), it could be a similar case to the CoRoT-7b super Earth (Léger et al. 2009). Photometry isplanned for this source in 2009 to discard a CEB scenario.

Hoping it is not a false positive or something else. Let's cross fingers.


47) OGLE-TR-10 and transiting exoplanet "Carystos": now I imagine NuclearVacuum giggling and blushing *lol*.

Edasich's Work - Page 2 OGLE-TR-10andNebula


Serendipitously I've noticed the Lagoon Nebula (M8) painting OGLE-TR-10 exoplanet host firmament. Suggestive, ain't it? Edasich's Work - Page 2 Icon_biggrin


48) HAT-P-11: transiting hot-neptune from HATNET, a Gliese 436 b's kin. Common name? Iphicles ! Edasich's Work - Page 2 Icon_wink

Hints of a secondary transit in the CoRoT candidate would hint that the candidate is of significant brightness compared to the host star. The secondary transits of super-Earths are probably not detectable with CoRoT, or even Kepler.

It's been Edasich's birthday yesterday, but curiously it's Edasich making presents. This time non-exoplanetary stuff. Had fun with unusual planetary nebulas:

49) Planetary Nebula He 2-138: popped up on October 27 at ArXiv. Central star is very hot O subdwarf.

Edasich's Work - Page 2 PNHe2-138


50) Waterfountain Nebula GLMP 480: randomly picked. Basd on IR reconstruction. Star is likely a dying late-M supergiant.

Little thread bump. I realized that saving Celestia snapshots as Portable Network Graphics (PNG) files, pictures look much neater than they do in common jpg files. Smile


51) Gliese 676 A and jovian kin "Eumon"

Edasich's Work - Page 2 Eumon


Putting coordinates into stc file for Celestia, you get the binary system being 3.62 light years away from another well-known exoplanet host, Mu Arae. Curious, ain't it?

Btw faint stellar components appear separated 758 AUs away each other. The red dot at planet's left is indeed GJ 676 B, a dim M3 dwarf.


52) Gliese 832 b: Another (cold) jovian around M dwarf.

Edasich's Work - Page 2 Gliese832b


53) NN Serpentis: WD+dM eclipsing binary...

Edasich's Work - Page 2 NNSerpentisbinary


... and their (putative) substellar/planetary companion

Edasich's Work - Page 2 NNSerpentisplanet


From parameters I've got in a previous paper about this system, I get a total luminosity of 0.044 LSolar. So water zone should be located nearly at 0.2 AUs.

See you next update Wink

Nice textures again =). Yeah I've got to get around to putting Gliese 676 into Celestia. Close to Mu Arae eh? That's neat.
