A celestial matryoshka: Dynamical and spectroscopic analysis of the Albireo system

Ronald Drimmel, Alessandro Sozzetti, Klaus-Peter Schroeder +4

We present a spectroscopic characterisation and a new orbital solution for the binary system beta Cyg Aa/Ac (MCA 55), the primary component (beta Cyg A) of the well-known wide doub…

The GAPS Programme at TNG XXVIII -- A pair of hot-Neptunes orbiting the young star TOI-942

Ilaria Carleo, Silvano Desidera, Domenico Nardiello +48

Both young stars and multi-planet systems are primary objects that allow us to study, understand and constrain planetary formation and evolution theories. We validate the physical…

HADES RV Programme with HARPS-N at TNG XII. The abundance signature of M dwarf stars with planets

J. Maldonado, G. Micela, M. Baratella +27

Most of our current knowledge on planet formation is still based on the analysis of main-sequence, solar-type stars. Conversely, detailed chemical studies of large samples of M-dwa…

Identifying Exoplanets with Deep Learning. IV. Removing Stellar Activity Signals from Radial Velocity Measurements Using Neural Networks

Zoe L. de Beurs, Andrew Vanderburg, Christopher J. Shallue +24

Exoplanet detection with precise radial velocity (RV) observations is currently limited by spurious RV signals introduced by stellar activity. We show that machine learning techniq…

K2-111: an old system with two planets in near-resonance

A. Mortier, M. R. Zapatero Osorio, L. Malavolta +64

This paper reports on the detailed characterisation of the K2-111 planetary system with K2, WASP, and ASAS-SN photometry as well as high-resolution spectroscopic data from HARPS-N…

An unusually low density ultra-short period super-Earth and three mini-Neptunes around the old star TOI-561

G. Lacedelli, L. Malavolta, L. Borsato +38

Based on HARPS-N radial velocities (RVs) and TESS photometry, we present a full characterisation of the planetary system orbiting the late G dwarf TOI-561. After the identification…

Three Years of HARPS-N High-Resolution Spectroscopy and Precise Radial Velocity Data for the Sun

X. Dumusque, M. Cretignier, D. Sosnowska +35

The solar telescope connected to HARPS-N has been observing the Sun since the summer of 2015. Such high-cadence, long-baseline data set is crucial for understanding spurious radial…

The GAPS Programme at TNG XXVII. Reassessment of a young planetary system with HARPS-N: is the hot Jupiter V830 Tau b really there?

M. Damasso, A. F. Lanza, S. Benatti +41

Detecting and characterising exoworlds around very young stars (age10 Myr) are key aspects of exoplanet demographic studies, especially for understanding the mechanisms and time…

The GAPS Programme at TNG -- XXIV. An eccentric Neptune-mass planet near the inner edge of the BD-11 4672 habitable zone

D. Barbato, M. Pinamonti, A. Sozzetti +34

With the growth of comparative exoplanetology, it is increasingly clear that investigating the relationships between inner and outer planets plays a key role in discriminating betw…

TOI-1235 b: a keystone super-Earth for testing radius valley emergence models around early M dwarfs

Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin +85

Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of the…

A pair of TESS planets spanning the radius valley around the nearby mid-M dwarf LTT 3780

Ryan Cloutier, Jason D. Eastman, Joseph E. Rodriguez +84

We present the confirmation of two new planets transiting the nearby mid-M dwarf LTT 3780 (TIC 36724087, TOI-732, , , =0.374 R, =0.401 M$_{\…
