The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert

S. Dreizler, I., J. +134

We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…

The Magellan-TESS Survey I: Survey Description and Mid-Survey Results

Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66

revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…

TOI 122b and TOI 237b, two small warm planets orbiting inactive M dwarfs, found by \textit{TESS}

William C. Waalkes, Zachory K. Berta-Thompson, Karen A. Collins +39

We report the discovery and validation of TOI 122b and TOI 237b, two warm planets transiting inactive M dwarfs observed by \textit{TESS}. Our analysis shows TOI 122b has a radius o…

TOI-954 b and K2-329 b: Short-Period Saturn-Mass Planets that Test whether Irradiation Leads to Inflation

Lizhou Sha, Chelsea X. Huang, Avi Shporer +70

We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, , ) observed in TESS sectors 4 and 5…

A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776

R. Luque, L. M. Serrano, K. Molaverdikhani +63

We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54+-0.03 Msun) detected during Sector 10 o…

TESS Reveals a Short-period Sub-Neptune Sibling (HD 86226c) to a Known Long-period Giant Planet

Johanna Teske, Matías R. Díaz, Rafael Luque +44

The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here we present the detection and mass measurement of a small…

TOI-1235 b: a keystone super-Earth for testing radius valley emergence models around early M dwarfs

Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin +85

Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of the…

TESS discovery of a super-Earth and three sub-Neptunes hosted by the bright, Sun-like star HD 108236

Tansu Daylan, Kartik Pingle, Jasmine Wright +59

We report the discovery and validation of four extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD~108236 using data from the Transiting Exoplanet Survey Satell…

Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?

P. Bluhm, R. Luque, N. Espinoza +78

We report the confirmation of a transiting planet around the bright, inactive M0.5 V star TOI-1235 (TYC 4384-1735-1, V = 11.5 mag), whose transit signal was detected in the photome…

A remnant planetary core in the hot-Neptune desert

David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91

The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…

A pair of TESS planets spanning the radius valley around the nearby mid-M dwarf LTT 3780

Ryan Cloutier, Jason D. Eastman, Joseph E. Rodriguez +84

We present the confirmation of two new planets transiting the nearby mid-M dwarf LTT 3780 (TIC 36724087, TOI-732, , , =0.374 R, =0.401 M$_{\…
