A Hot Saturn Orbiting an Oscillating Late Subgiant Discovered by TESS

Jonathan Gagné, J.-D. do Nascimento, Andrés Jordán, A. Mazumdar et autres

We present the discovery of HD 221416 b, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is possible. HD 221416 b (HIP 116158, TOI-197) is a bright (V = 8.2 mag), …

TOI-1452 b: SPIRou and TESS Reveal a Super-Earth in a Temperate Orbit Transiting an M4 Dwarf

Charles Cadieux, René Doyon, Mykhaylo Plotnykov, G. Hébrard et autres

Abstract Exploring the properties of exoplanets near or inside the radius valley provides insight on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini-Neptunes. Here, we report the discovery of TOI-1452b, a transiting super-Earth (R p = 1.67 ± …

TOI-1201 b: A mini-Neptune transiting a bright and moderately young M dwarf

D. Kossakowski, J. Kemmer, P. Bluhm, S. Stock et autres

We present the discovery of a transiting mini-Neptune around TOI-1201, a relatively bright and moderately young early M dwarf (J ≈ 9.5 mag, ~600–800 Myr) in an equal-mass ~8 arcsecond-wide binary system, using data from the Transiting Exoplanet Survey Satellite, along with …

TOI-1201 b: A mini-Neptune transiting a bright and moderately young M dwarf

D. Kossakowski, J. Kemmer, P. Bluhm, S. Stock et autres

We present the discovery of a transiting mini-Neptune around TOI-1201, a relatively bright and moderately young early M dwarf ($J \approx$ 9.5 mag, $\sim$600-800 Myr) in an equal-mass $\sim$8 arcsecond-wide binary system, using data from the Transiting Exoplanet Survey Satellite (TESS), along …

TOI-824 b: A New Planet on the Lower Edge of the Hot Neptune Desert

Jennifer Burt, Louise D. Nielsen, Samuel N. Quinn, Eric E. Mamajek et autres

Abstract We report the detection of a transiting hot Neptune exoplanet orbiting TOI-824 ( SCR J1448-5735 ), a nearby (d = 64 pc) K4V star, using data from the Transiting Exoplanet Survey Satellite. The newly discovered planet has a radius R p …

Gravity-darkening Analysis of the Misaligned Hot Jupiter MASCARA-4 b

John P. Ahlers, Ethan Kruse, Knicole D. Colón, Patrick Dorval et autres

MASCARA-4 b is a hot Jupiter in a highly misaligned orbit around a rapidly rotating A3V star that was observed for 54 days by the iTransiting Exoplanet Survey Satellite (TESS)/i. We perform two analyses of MASCARA-4 b using a stellar gravity-darkened model. …

The Transiting Multi-planet System HD15337: Two Nearly Equal-mass Planets Straddling the Radius Gap

D. Gandolfi, L. Fossati, John H. Livingston, Keivan G. Stassun et autres

We report the discovery of a super-Earth and a sub-Neptune transiting the star HD 15337 (TOI-402, TIC 120896927), a bright (V = 9) K1 dwarf observed by the Transiting Exoplanet Survey Satellite (TESS) in Sectors 3 and 4. We combine the TESS …

Near-resonance in a System of Sub-Neptunes from TESS

Samuel N. Quinn, Juliette Becker, Joseph E. Rodriguez, Sam Hadden et autres

We report the Transiting Exoplanet Survey Satellite detection of a multi-planet system orbiting the V = 10.9 K0 dwarf TOI-125. We find evidence for up to five planets, with varying confidence. Three transit signals with high signal-to-noise ratio correspond to sub-Neptune-sized planets …
