Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…
ESA Voyage 2050 white paper -- Faint objects in motion: the new frontier of high precision astrometry
F. Malbet, U. Abbas, J. Alves +28
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Using HARPS-N to characterise the long-period planets in the PH-2 and Kepler-103 systems
Sophie C. Dubber, Annelies Mortier, Ken Rice +26
We present confirmation of the planetary nature of PH-2b, as well as the first mass estimates for the two planets in the Kepler-103 system. PH-2b and Kepler-103c are both long-peri…
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…
Biases in retrieving planetary signals in the presence of quasi-periodic stellar activity
M. Damasso, M. Pinamonti, G. Scandariato +1
Gaussian process regression is a widespread tool used to mitigate stellar correlated noise in radial velocity time series. It is particularly useful to search for and determine the…
ESA Voyage 2050 White Paper: Detecting life outside our solar system with a large high-contrast-imaging mission
Ignas Snellen, Simon Albrecht, Guillem Anglada-Escude +64
In this white paper, we recommend the European Space Agency plays a proactive role in developing a global collaborative effort to construct a large high-contrast imaging space tele…
An 11 Earth-Mass, Long-Period Sub-Neptune Orbiting a Sun-like Star
Andrew W. Mayo, Vinesh M. Rajpaul, Lars A. Buchhave +27
Although several thousands of exoplanets have now been detected and characterized, observational biases have led to a paucity of long-period, low-mass exoplanets with measured mass…
Atmospheric characterization of terrestrial exoplanets in the mid-infrared: biosignatures, habitability & diversity
Sascha P. Quanz, Olivier Absil, Daniel Angerhausen +45
Exoplanet science is one of the most thriving fields of modern astrophysics. A major goal is the atmospheric characterization of dozens of small, terrestrial exoplanets in order to…
Voyage 2050 White Paper: All-Sky Visible and Near Infrared Space Astrometry
David Hobbs, Anthony Brown, Erik Høg +27
A new all-sky visible and Near-InfraRed (NIR) space astrometry mission with a wavelength cutoff in the K-band is not just focused on a single or small number of key science cases.…
Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations
J. Maldonado, D. F. Phillips, X. Dumusque +29
(Abridged) We perform a detailed study of the main optical activity indicators (Ca II H & K, Balmer lines, Na I D D, and He I D) measured for the Sun…
The Revised TESS Input Catalog and Candidate Target List
Keivan G. Stassun, Ryan J. Oelkers, Martin Paegert +33
We describe the catalogs assembled and the algorithms used to populate the revised TESS Input Catalog (TIC), based on the incorporation of the Gaia second data release. We also des…
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…
All-Sky Near Infrared Space Astrometry
Barbara McArthur, David Hobbs, Erik Høg +20
Gaia is currently revolutionizing modern astronomy. However, much of the Galactic plane, center and the spiral arm regions are obscured by interstellar extinction, rendering them i…
The HADES RV Programme with HARPS-N at TNG XI. GJ 685 b: a warm super-Earth around an active M dwarf
M. Pinamonti, A. Sozzetti, P. Giacobbe +23
Small rocky planets seem to be very abundant around low-mass M-type stars. Their actual planetary population is however not yet precisely understood. Currently several surveys aim…
Wide-Orbit Exoplanet Demographics
David P. Bennett, Rachel Akeson, Yann Alibert +41
The Kepler, K2 and TESS transit surveys are revolutionizing our understanding of planets orbiting close to their host stars and our understanding of exoplanet systems in general, b…
Gliese 49: Activity evolution and detection of a super-Earth
M Perger, G Scandariato, I Ribas +40
Small planets around low-mass stars often show orbital periods in a range that corresponds to the temperate zones of their host stars which are therefore of prime interest for plan…
