Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS

Kavli Affiliate: Gabor Furesz | First 5 Authors: Angelica Psaridi, François Bouchy, Monika Lendl, Babatunde Akinsanmi, Keivan G. Stassun | Summary: While the sample of confirmed exoplanets continues to increase, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a […]

Stability and detectability of exomoons orbiting HIP 41378 f, a temperate Jovian planet with an anomalously low apparent density

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Caleb K. Harada, Courtney D. Dressing, Munazza K. Alam, James Kirk, Mercedes Lopez-Morales | Summary: Moons orbiting exoplanets ("exomoons") may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the temperate ($T_text{eq}=294$ K) giant ($R = 9.2$ R$_oplus$) […]

TIC 219006972: A Compact, Coplanar Quadruple Star System Consisting of Two Eclipsing Binaries with an Outer Period of 168 days

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Veselin B. Kostov, Tamas Borkovits, Saul A. Rappaport, Brian P. Powell, Andras Pal | Summary: We present the discovery of a new highly compact quadruple star system, TIC 219006972, consisting of two eclipsing binary stars with orbital periods of 8.3 days and 13.7 days, and an […]

Orbital decay in an accreting and eclipsing 13.7 minute orbital period binary with a luminous donor

Kavli Affiliate: Saul Rappaport | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Saul Rappaport, Tin Long Sunny Wong, Evan B. Bauer | Summary: We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. The system contains a white dwarf accretor, which likely originated as a post-common […]

The dark matter profile of the Milky Way inferred from its circular velocity curve

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anna-Christina Eilers, Lina Necib, Anna Frebel, | Summary: In this paper, we construct the circular velocity curve of the Milky Way out to $sim 30$ kpc, providing an updated model of the dark matter density profile. We derive precise parallaxes for 120,309 stars with a […]
