Edasich's Work

"When the lions broke free", quoting someway Pink Floyd *lol*

A little thread bump for two systems in Leo constellation:


54) Gamma1 Leonis and planet: K-giant in binary system with hot jupiter.




Notice the secondary star at periastron getting as close as 10.7 AUs from star A.




55) R Leonis: Mira variable star




...with evaporating planet

great work! continue to keep alive our dreams!

Oh a new member!

Thank you for kind support

Wow, that's beautiful ! It will make you laugh but I think that the planet is taking a bath. But it also make me think that the cloud forms a wall in front of the planet (or a shock wave), such as the case of Mira.
Can you make a pic of the planet as a observer would see above its terminator ?

I could try. Give me some time to edit ssc file and models

Don't worry about that, I will wait.

I don't know if this is what Sedna requested. Enjoy it anyway
The host star really appears like a monster, even if the planet lies in "quasi-epistellar" orbit




I was taking looking at thread visits. Gosh! More than 1,700!
Thank you all, pals!

Screenshots like that emphasize the need for Celestia to render light sources as something other than point-like. Much more of that planet should be illuminated than is shown in Celestia.

Wouldn't a hypothetical R Leo b just kinda fall into the star anyway?

Don't get too excited, half of them are yours

Sorry, Sirius, but here I come always and only for thread bumps, you envious dude *lol* Hehehehe


56) - For those who like "freshly baked cookies": QS Virginis cataclysmic-variable...



...and extrasolar planet candidate QS Vir b (or QS Vir C?).

Howww, it's better than I expected. We clearly see the wall of gas. Great work Edasich !

The red dwarf in the QS Vir system fills its Roche lobe so should be shaped like a teardrop.

For space artists, it's an unfortunate feature of both QS Vir and HW Vir that the binaries are so compact that it would be hard to make out the two stars from the vantage point of the planets.

Congratulations, Edasich!!

First Celestia add-on accepted made by Edasich!

QS Virginis and planet

Quote :

This addon has been rated as: Excellent

Emphasis mine. Rating not.

However bear in mind that QS Virginis is now included in the default extrasolar.ssc and extrasolar.stc files - these can be downloaded from the Celestia Subversion repository here.

Personally I build my version of Celestia from source, and keep up-to-date with the latest features and datafiles.

I know, but I don't know if the extrasolar.stc files generates the binary system too.
The add-on I made includes the binary, with accurate parameters (lacking only of the tidally distorted appearance you said) and my own planet texture.

It does. However it too does not contain the tidally-distorted appearance. Main difference is it is currently lacking the eccentricity information for the planetary orbit, however this is likely going to be included in the next version of the files.

Lazarus, can the script you wrote to create contact binaries produce the necessary shape for this star?

Not without making a few modifications. Would require different bounding constraints for a start. Also the fill-out-factor used for contact binaries isn't so useful here, so would have to change a few of the parameters. Also I'm not entirely sure what the most sensible way to uv-map such a star would be.

This is the wikipedia page of "Tyrogthekreeper" (that is Edasich in disguise *lol*). There I've put several Celestia pictures of exoplanets.

http://en.wikipedia.org/wiki/Category:User:Tyrogthekreeper/Images

Some teasers:

57) - Pi2 Ursae Majoris b.



58) VB 10 b.



59) Microlensing planet MOA-2007-BLG-400-Lb.



60) White dwarf planet GD 66 b.

Have you checked out the addon for celestia that does W UMa type stars?

Lazarus is actually quite familiar with that add-on, yes.
He made it.

Edasich, some time you should teach me how to make such amazing gas giant textures

I think we'd all like to know how he does such great stuff!

Little thread bump about the awesome system of:

61) WASP-18 b: now also available as Celestia AddOn!!

WASP-18 b for Celestia

WASP-18b is in the latest versions of the extrasolar.ssc/.stc files found on the Celestia Subversion repository.

Also bear in mind that Celestia by default requires orbital elements to be given in the ecliptic reference frame, not the plane-of-sky reference frame used for planets. Your add-on therefore fails to produce the correct orbital inclination.

Furthermore the rotation of the planet and the orbit are not aligned, despite being synchronous. Not sure if that was your intention.

A teaser:

62) GJ 1214 b: transiting Super-Earth with low-density.




No information for no embargo breach.

63) OGLE-2007-BLG-368L b: Neptune's analog (though less cold).




64) Nu Ophiuchi & Tau Geminorum: who remembers their brown dwarfs?

Guess who's done that exoplanet picture in featured articles, folks...
