Buldgen G, Pain J, Cosse P, Blancard C, Gilleron F, Pradhan A, et al.
Nat Commun . 2025 Jan; 16(1):693. PMID: 39870621
The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the...

Thompson S, Coughlin J, Hoffman K, Mullally F, Christiansen J, Burke C, et al.
Astrophys J Suppl Ser . 2020 Sep; 235(2). PMID: 32908325
We present the Kepler Object of Interest (KOI) catalog of transiting exoplanets based on searching four years of time series photometry (Data Release 25, Q1-Q17). The catalog contains 8054 KOIs...

Huber D, Carter J, Barbieri M, Miglio A, Deck K, Fabrycky D, et al.
Science . 2013 Oct; 342(6156):331-4. PMID: 24136961
Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple coplanar planets have been seen to have low obliquities. This has been interpreted as evidence...

Borucki W, Agol E, Fressin F, Kaltenegger L, Rowe J, Isaacson H, et al.
Science . 2013 Apr; 340(6132):587-90. PMID: 23599262
We present the detection of five planets--Kepler-62b, c, d, e, and f--of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii (R⊕), orbiting a K2V star at periods of 5.7,...

Barclay T, Rowe J, Lissauer J, Huber D, Fressin F, Howell S, et al.
Nature . 2013 Feb; 494(7438):452-4. PMID: 23426260
Since the discovery of the first exoplanets, it has been known that other planetary systems can look quite unlike our own. Until fairly recently, we have been able to probe...

Carter J, Agol E, Chaplin W, Basu S, Bedding T, Buchhave L, et al.
Science . 2012 Jun; 337(6094):556-9. PMID: 22722249
In the solar system, the planets' compositions vary with orbital distance, with rocky planets in close orbits and lower-density gas giants in wider orbits. The detection of close-in giant planets...

Beck P, Montalban J, Kallinger T, De Ridder J, Aerts C, Garcia R, et al.
Nature . 2011 Dec; 481(7379):55-7. PMID: 22158105
When the core hydrogen is exhausted during stellar evolution, the central region of a star contracts and the outer envelope expands and cools, giving rise to a red giant. Convection...

Bedding T, Mosser B, Huber D, Montalban J, Beck P, Christensen-Dalsgaard J, et al.
Nature . 2011 Apr; 471(7340):608-11. PMID: 21455175
Red giants are evolved stars that have exhausted the supply of hydrogen in their cores and instead burn hydrogen in a surrounding shell. Once a red giant is sufficiently evolved,...

Borucki W, Koch D, Basri G, Batalha N, Brown T, Caldwell D, et al.
Science . 2010 Jan; 327(5968):977-80. PMID: 20056856
The Kepler mission was designed to determine the frequency of Earth-sized planets in and near the habitable zone of Sun-like stars. The habitable zone is the region where planetary temperatures...
