TESS Duotransit Candidates from the Southern Ecliptic Hemisphere

Faith Hawthorn, Sam Gill, Daniel Bayliss +20

Discovering transiting exoplanets with long orbital periods allows us to study warm and cool planetary systems with temperatures similar to the planets in our own Solar system. The…

Separated twins or just siblings? A multi-planet system around an M dwarf including a cool sub-Neptune

Mallory Harris, Diana Dragomir, Ismael Mireles +27

We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS Sector 12 wit…

TOI-199 b: A well-characterized 100-day transiting warm giant planet with TTVs seen from Antarctica

Melissa J. Hobson, Trifon Trifonov, Thomas Henning +49

We present the spectroscopic confirmation and precise mass measurement of the warm giant planet TOI-199 b. This planet was first identified in TESS photometry and confirmed using g…

TOI-4600 b and c: Two long-period giant planets orbiting an early K dwarf

Ismael Mireles, Diana Dragomir, Hugh P. Osborn +31

We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 (V=12.6, T=11.9), first detected using observations from the Transiti…

TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906

Amy Tuson, Didier Queloz, Hugh P. Osborn +119

We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…

Refined parameters of the HD 22946 planetary system and the true orbital period of planet d

Z. Garai, H. P. Osborn, D. Gandolfi +85

Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…

Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops

Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126

HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …

TOI-5678 b: A 48-day transiting Neptune-mass planet characterized with CHEOPS and HARPS

S. Ulmer-Moll, H. P. Osborn, A. Tuson +92

A large sample of long-period giant planets has been discovered thanks to long-term radial velocity surveys, but only a few dozen of these planets have a precise radius measurement…

Three long period transiting giant planets from TESS

Rafael Brahm, Solène Ulmer-Moll, Melissa J. Hobson +52

We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the…

Discovery of a massive giant planet with extreme density around a sub-giant star TOI-4603

Akanksha Khandelwal, Rishikesh Sharma, Abhijit Chakraborty +11

We present the discovery of a transiting massive giant planet around TOI-4603, a sub-giant F-type star from NASA's Transiting Exoplanet Survey Satellite (TESS). The newly discovere…

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

Angelica Psaridi, François Bouchy, Monika Lendl +62

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 investig…
