Planets Around Solar Twins/Analogs (PASTA) I.: High precision stellar chemical abundance for 17 planet-hosting stars and the condensation temperature trend
Qinghui Sun, Sharon Xuesong Wang, Tianjun Gan +30
The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, hi…

OrCAS: Origins, Compositions, and Atmospheres of Sub-neptunes. I. Survey Definition
Ian J. M. Crossfield, Alex S. Polanski, Paul Robertson +61
Sub-Neptunes - volatile-rich exoplanets smaller than Neptune - are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well a…
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…
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…
An Earth-sized Planet on the Verge of Tidal Disruption
Fei Dai, Andrew W. Howard, Samuel Halverson +95
TOI-6255~b (GJ 4256) is an Earth-sized planet (1.079 ) with an orbital period of only 5.7 hours. With the newly commissioned Keck Planet Finder (KPF) and CARMEN…
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-1408: Discovery and Photodynamical Modeling of a Small Inner Companion to a Hot Jupiter Revealed by TTVs
Judith Korth, Priyanka Chaturvedi, Hannu Parviainen +60
We report the discovery and characterization of a small planet, TOI-1408 c, on a 2.2-day orbit located interior to a previously known hot Jupiter, TOI-1408 b ( d, $M=1.86\p…
Surviving in the Hot Neptune Desert: The Discovery of the Ultra-Hot Neptune TOI-3261b
Emma Nabbie, Chelsea X. Huang, Jennifer A. Burt +45
The recent discoveries of Neptune-sized ultra-short period planets (USPs) challenge existing planet formation theories. It is unclear whether these residents of the Hot Neptune Des…
A transiting multi-planet system in the 61 million year old association Theia 116
Sydney Vach, George Zhou, Chelsea X. Huang +28
Observing and characterizing young planetary systems can aid in unveiling the evolutionary mechanisms that sculpt the mature exoplanet population. As an all-sky survey, NASA's Tran…
