TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs

Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson +92

We validate the presence of a two-planet system orbiting the 0.15--1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune…

The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf

O. Barragán, D. J. Armstrong, D. Gandolfi +103

We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…

The LHS 1678 System: Two Earth-Sized Transiting Planets and an Astrometric Companion Orbiting an M Dwarf Near the Convective Boundary at 20 pc

Michele L. Silverstein, Joshua E. Schlieder, Thomas Barclay +48

We present the TESS discovery of the LHS 1678 (TOI-696) exoplanet system, comprised of two approximately Earth-sized transiting planets and a likely astrometric brown dwarf orbitin…

TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet

Ares Osborn, David J. Armstrong, Bryson Cale +125

We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…

Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit

Nolan Grieves, François Bouchy, Monika Lendl +52

We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…

A transit timing variation observed for the long-period extremely low density exoplanet HIP 41378f

Edward M. Bryant, Daniel Bayliss, Alexandre Santerne +47

HIP 41378 f is a temperate planet with period of 542.08 days and an extremely low density of g cm. It transits the bright star HIP 41378…

Warm Jupiters in TESS Full-Frame Images: A Catalog and Observed Eccentricity Distribution for Year 1

Jiayin Dong, Chelsea X. Huang, Rebekah I. Dawson +57

Warm Jupiters -- defined here as planets larger than 6 Earth radii with orbital periods of 8--200 days -- are a key missing piece in our understanding of how planetary systems form…

A nearby transiting rocky exoplanet that is suitable for atmospheric investigation

T. Trifonov, J. A. Caballero, J. C. Morales +66

Spectroscopy of transiting exoplanets can be used to investigate their atmospheric properties and habitability. Combining radial velocity (RV) and transit data provides additional…

The SPHERE infrared survey for exoplanets (SHINE)- I Sample definition and target characterization

S. Desidera, G. Chauvin, M. Bonavita +105

Large surveys with new-generation high-contrast imaging instruments are needed to derive the frequency and properties of exoplanet populations with separations from 5 to 300…

TESS Hunt for Young and Maturing Exoplanets (THYME) IV: Three small planets orbiting a 120 Myr-old star in the Pisces--Eridanus stream

Elisabeth R. Newton, Andrew W. Mann, Adam L. Kraus +50

Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC…

TIC 168789840: A Sextuply-Eclipsing Sextuple Star System

Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport +48

We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three…
