SOPHIE and TESS characterization of fourteen TESS Objects of Interest: nine planetary systems and five low-mass stellar companions

N. Heidari, G. Hébrard, S. Sousa +61

We present fourteen TESS Objects of Interest (TOIs) from the SOPHIE-TESS follow-up program. Combining TESS photometry, SOPHIE radial velocities (RVs), ground-based photometry, and…

TS23/McDonald and FIES/NOT strike again. Two new warm Jupiter systems and outer companions in a third

E. Knudstrup, D. Gandolfi, W. D. Cochran +29

Warm Jupiters (gas giant planets with orbital periods of P8-200 d) are thought to be largely unaffected by the tidal interactions that can erase information about the dynamic…

Characterization of two new transiting sub-Neptunes and a terrestrial planet around M-dwarf hosts

E. Poultourtzidis, G. Lacedelli, E. Pallé +49

We report the confirmation of three transiting exoplanets orbiting TOI-1243 (LSPM~J0902+7138), TOI-4529 (G~2--21), and TOI-5388 (Wolf~346) that were initially detected by TESS thro…

Sibling Sub-Neptunes Around Sibling M Dwarfs: TOI-521 and TOI-912

G. Lacedelli, E. Pallé, R. Luque +47

Sub-Neptunes are absent in the Solar System, yet they are commonly found in our Galaxy. They challenge the internal structure models and prompt investigation on their formation, ev…

TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet

K. Barkaoui, J. Korth, E. Gaidos +119

TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…

The GAPS Programme at TNG. LXV. Precise density measurement of TOI-1430 b, a young planet with an evaporating atmosphere

D. Nardiello, J. M. Akana Murphy, R. Spinelli +34

Small-sized exoplanets in tight orbits around young stars (10-1000 Myr) give us the opportunity to investigate the mechanisms that led to their formation, the evolution of their ph…

Validation of up to seven TESS planet candidates through multi-colour transit photometry using MuSCAT2 data

A. Peláez-Torres, E. Esparza-Borges, E. Pallé +62

The TESS mission searches for transiting exoplanets by monitoring the brightness of hundreds of thousands of stars across the entire sky. M-type planet hosts are ideal targets for…

TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit

A. Alqasim, N. Grieves, N. M. Rosário +129

We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…

TOI-2084 b and TOI-4184 b: two new sub-Neptunes around M dwarf stars

K. Barkaoui, M. Timmermans, A. Soubkiou +67

We present the discovery and validation of two TESS exoplanets orbiting nearby M dwarfs: TOI-2084b, and TOI-4184b. We characterized the host stars by combining spectra from Shane/K…

Validation of 13 Hot and Potentially Terrestrial TESS Planets

Steven Giacalone, Courtney D. Dressing, Christina Hedges +108

The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially…

Two new HATNet hot Jupiters around A stars, and the first glimpse at the occurrence rate of hot Jupiters from TESS

G. Zhou, C. X. Huang, G. Á. Bakos +68

Wide field surveys for transiting planets are well suited to searching diverse stellar populations, enabling a better understanding of the link between the properties of planets an…

A dearth of small particles in the transiting material around the white dwarf WD 1145+017

S. Xu, S. Rappaport, R. van Lieshout +35

White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and e…
