Variable red- and blue-shifted absorption features observed in the Ca ii K line towards the A-type shell star Leo have been suggested by us in a previous work to be likely due…
Constraining the solar neighbourhood age-metallicity relation from white dwarf-main sequence binaries
A. Rebassa-Mansergas, J. Maldonado, R. Raddi +11
The age-metallicity relation is a fundamental tool for constraining the chemical evolution of the Galactic disc. In this work we analyse the observational properties of this relati…

T. W. Milbourne, D. F. Phillips, N. Langellier +21
State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Five carbon- and nitrogen-bearing species in a hot giant planet's atmosphere
Paolo Giacobbe, Matteo Brogi, Siddharth Gandhi +40
The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot Jupiters) have been probed for nearly two decades. They allow us to investigate the chemical a…
A super-Earth on a close-in orbit around the M1V star GJ 740. A HADES and CARMENES collaboration
B. Toledo-Padrón, A. Suárez Mascareño, J. I. González Hernández +23
M-dwarfs have proven to be ideal targets for planetary radial velocity (RV) searches due to their higher planet-star mass contrast. The HADES and CARMENES programs aim to carry out…
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…
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…
Detection Limits of Low-mass, Long-period Exoplanets Using Gaussian Processes Applied to HARPS-N Solar RVs
N. Langellier, T. W. Milbourne, D. F. Phillips +29
Radial velocity (RV) searches for Earth-mass exoplanets in the habitable zone around Sun-like stars are limited by the effects of stellar variability on the host star. In particula…
GJ 357 b: A Super-Earth Orbiting an Extremely Inactive Host Star
D. Modirrousta-Galian, B. Stelzer, E. Magaudda +5
In this paper we present a deep X-ray observation of the nearby M dwarf GJ 357 and use it to put constraints on the atmospheric evolution of its planet, GJ 357 b. We also analyse t…
The GAPS Programme at TNG -- XXIII. HD 164922 d: a close-in super-Earth discovered with HARPS-N in a system with a long-period Saturn mass companion
S. Benatti, M. Damasso, S. Desidera +41
In the framework of the Global Architecture of Planetary Systems (GAPS) project we collected more than 300 spectra with HARPS-N at the TNG for the bright G9V star HD164922. This ta…
The GAPS Programme at TNG XXI -- A GIARPS case-study of known young planetary candidates: confirmation of HD 285507 b and refutation of AD Leo b
I. Carleo, L. Malavolta, A. F. Lanza +67
The existence of hot Jupiters is still not well understood. Two main channels are thought to be responsible for their current location: a smooth planet migration through the proto-…
Testing the Spectroscopic Extraction of Suppression of Convective Blueshift
M. Miklos, T. W. Milbourne, R. D. Haywood +21
Efforts to detect low-mass exoplanets using stellar radial velocities (RVs) are currently limited by magnetic photospheric activity. Suppression of convective blueshift is the domi…
HR 10: A main-sequence binary with circumstellar envelopes around both components. Discovery and analysis
B. Montesinos, C. Eiroa, J. Lillo-Box +16
This paper is framed within a large project devoted to studying the presence of circumstellar material around main sequence stars, and looking for exocometary events. The work conc…
Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations

Three years of Sun-as-a-star radial-velocity observations on the approach to solar minimum
A. Collier Cameron, A. Mortier, D. Phillips +33
The time-variable velocity fields of solar-type stars limit the precision of radial-velocity determinations of their planets' masses, obstructing detection of Earth twins. Since 20…
Connecting substellar and stellar formation. The role of the host star's metallicity
J. Maldonado, E. Villaver, C. Eiroa +1
Most of our current understanding of the planet formation mechanism is based on the planet metallicity correlation derived mostly from solar-type stars harbouring gas-giant planets…
Gliese 49: Activity evolution and detection of a super-Earth
