Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS
N. Heidari, G. H'ebrard, E. Martioli +65
We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…
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…
TESS discovery of two super-Earths orbiting the M-dwarf stars TOI-6002 and TOI-5713 near the radius valley
M. Ghachoui, B. V. Rackham, M. Dévora-Pajares +45
We present the validation of two TESS super-Earth candidates transiting the mid-M dwarfs TOI-6002 and TOI-5713 every 10.90 and 10.44 days, respectively. The first star (TOI-6002) i…
The inflated, eccentric warm Jupiter TOI-4914 b orbiting a metal-poor star, and the hot Jupiters TOI-2714 b and TOI-2981 b
G. Mantovan, T. G. Wilson, L. Borsato +32
Recent observations of giant planets have revealed unexpected bulk densities. Hot Jupiters, in particular, appear larger than expected for their masses compared to planetary evolut…
Characterisation of TOI-406 as showcase of the THIRSTEE program: A 2-planet system straddling the M-dwarf density gap
G. Lacedelli, E. Pallè, R. Luque +31
The exoplanet sub-Neptune population currently poses a conundrum, as to whether small-size planets are volatile-rich cores without an atmosphere, or rocky cores surrounded by a H-H…
K2-399 b is not a planet. The Saturn that wandered through the Neptune desert is actually a hierarchical eclipsing binary
J. Lillo-Box, D. W. Latham, K. A. Collins +19
The transit technique has been very efficient in detecting planet candidate signals over the past decades. The so-called statistical validation approach has become a popular way of…
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…
Three short-period Earth-sized planets around M dwarfs discovered by TESS: TOI-5720b, TOI-6008b and TOI-6086b
K. Barkaoui, R. P. Schwarz, N. Narita +53
One of the main goals of the NASA's TESS (Transiting Exoplanet Survey Satellite) mission is the discovery of Earth-like planets around nearby M-dwarf stars. Here, we present the di…
Three super-Earths and a possible water world from TESS and ESPRESSO
M. J. Hobson, F. Bouchy, B. Lavie +51
Since 2018, the ESPRESSO spectrograph at the VLT has been hunting for planets in the Southern skies via the RV method. One of its goals is to follow up candidate planets from trans…
TOI-4336 A b: A temperate sub-Neptune ripe for atmospheric characterization in a nearby triple M-dwarf system
M. Timmermans, G. Dransfield, M. Gillon +54
Small planets transiting bright nearby stars are essential to our understanding of the formation and evolution of exoplanetary systems. However, few constitute prime targets for at…
NGTS-30 b/TOI-4862 b: An 1 Gyr old 98-day transiting warm Jupiter
M. P. Battley, K. A. Collins, S. Ulmer-Moll +63
Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of pl…
TOI-1199 b and TOI-1273 b: Two new transiting hot Saturns detected and characterized with SOPHIE and TESS
J. Serrano Bell, R. F. Díaz, G. Hébrard +41
We report the characterization of two planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-1199 b and TOI-1273 b, with periods of 3.7 and 4.6 days, r…
TOI-1135 b: A young hot Saturn-size planet orbiting a solar-type star
M. Mallorquín, N. Lodieu, V. J. S. Béjar +20
Despite the thousands of planets in orbit around stars known to date, the mechanisms of planetary formation, migration, and atmospheric loss remain unresolved. In this work, we con…
Wolf 327b: A new member of the pack of ultra-short-period super-Earths around M dwarfs
F. Murgas, E. Pallé, J. Orell-Miquel +52
Planets with orbital periods shorter than 1 day are rare and have formation histories that are not completely understood. Small () ultra-short-period (…
