Kepler-410 - A Neptune around a bright star

What asteroseismology can do for exoplanets: Kepler-410A b is a Small Neptune around a bright star, in an eccentric orbit consistent with low obliquity

We confirm the Kepler planet candidate Kepler-410b (KOI-42b) as a Neptune sized exoplanet on a 17.8 day, eccentric orbit around the bright (Kp = 9.4) star Kepler-410A. This is the third brightest confirmed planet host star in the Kepler field and one of the brightest hosts of all currently known transiting exoplanets. Kepler-410 consists of a blend between the fast rotating planet host star (Kepler-410A) and a fainter star (Kepler-410B), which has complicated the confirmation of the planetary candidate. Employing asteroseismology, using constraints from the transit light curve, adaptive optics and speckle images, and Spitzer transit observations, we demonstrate that the candidate can only be an exoplanet orbiting Kepler-410A. Via asteroseismology we determine the following stellar and planetary parameters with high precision; M⋆=1.214±0.033 M⊙, R⋆=1.352±0.010 R⊙, Age = 2.76±0.54 Gyr, planetary radius (2.838±0.054 R⊕), and orbital eccentricity (0.17+0.07−0.06). In addition, rotational splitting of the pulsation modes allows for a measurement of Kepler-410A's inclination and rotation rate. Our measurement of an inclination of 82.5+7.5−2.5 [∘] indicates a low obliquity in this system. Transit timing variations indicate the presence of at least one additional (non-transiting) planet in the system.

Looks like we may have skipped a few Kepler-#'s. Also, KOI-42 = HD 175289

Why Kepler-410?

Well that's quite a jump in the numbers... is someone doing an automated confirmation of hundreds of planet candidates or something?

Is there any word on whether the A and B stars are a physical binary or just unrelated stars that happen to lie close to the same line of sight?

Probably a typo, I presume.

If so, this "typo" is all through the paper. The paper offers frustratingly little information about the binarity of the system and information about the secondary star.   

Maybe there is ~320 confirmed Kepler systems in the publication process?  

320 it will be huge  

May be the result of a new method ?

206.06 – VALFAST: Secure Probabilistic Validation of Hundreds of Kepler Planet
Candidates

« …I present the results of applying VALFAST---a planet validation code based on the methodology
described in Morton (2012)---to every Kepler Object of Interest. VALFAST is unique in its combination of detail, completeness, and speed. Using the transit light curve shape, realistic population simulations, and (optionally) diverse follow-up observations, it calculates the probability that a transit candidate signal is the result of a true transiting planet or any of a number of astrophysical false positive scenarios, all in just a few minutes on a laptop computer. In addition to efficiently validating the planetary nature of hundreds of new KOIs, this broad application of VALFAST also demonstrates its ability to reliably identify likely false positives… »
