TESS Spots a Super-Puff: The Remarkably Low Density of TOI-1420b

Stephanie Yoshida, Shreyas Vissapragada, David W. Latham +51

We present the discovery of TOI-1420b, an exceptionally low-density ( g cm) transiting planet in a day orbit around a late G dwarf star. Using tra…

A super-massive Neptune-sized planet

L. Naponiello, L. Mancini, A. Sozzetti +55

Neptune-sized planets exhibit a wide range of compositions and densities, depending onf cators related to their formation and evolution history, such as the distance from their hos…

A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio

M. Damasso, J. Rodrigues, A. Castro-González +52

We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…

TOI-332 b: a super dense Neptune found deep within the Neptunian desert

Ares Osborn, David J. Armstrong, Jorge Fernández Fernández +49

To date, thousands of planets have been discovered, but there are regions of the orbital parameter space that are still bare. An example is the short period and intermediate mass/r…

An inner warp discovered in the disk around HD 110058 using VLT/SPHERE and HST/STIS

S. Stasevic, J. Milli, J. Mazoyer +16

An edge-on debris disk was detected in 2015 around the young, nearby A0V star HD 110058. The disk showed features resembling those seen in the disk of beta Pictoris that could indi…

The CORALIE survey for southern extrasolar planets XIX. Brown dwarfs and stellar companions unveiled by radial velocity and astrometry

D. Barbato, D. Ségransan, S. Udry +17

A historical planet-search on a sample of 1647 nearby southern main sequence stars has been ongoing since 1998 with the CORALIE spectrograph at La Silla Observatory, with a backup…
