Exoplanetary science is on the verge of an unprecedented revolution. The thousands of
exoplanets discovered over the past decade have most recently been supplemented by …

In this paper we present a catalog of 4584 eclipsing binaries observed during the first two
years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binary …

The activity of stars such as the Sun varies over timescales ranging from the very short to the
very long—stellar and planetary evolutionary timescales. Experience from our solar system …

Aims. We present a novel method for studying the thermal emission of exoplanets as a
function of orbital phase at very high spectral resolution, and use it to investigate the climate …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

Abstract The Large Array Survey Telescope (LAST) is designed to survey the variable and
transient sky at high temporal cadence. The array is comprised of 48 F/2.2 telescopes of …

Radial-velocity (RV) surveys have discovered hundreds of exoplanetary systems but suffer
from a fundamental degeneracy between planet mass M p and orbital inclination i. In this …

Over the last decade, precise exoplanet transmission spectroscopy has revealed the
atmospheres of dozens of exoplanets, driven largely by observatories like the Hubble Space …

Present and future high-precision radial-velocity spectrometers dedicated to the discovery of
low-mass planets orbiting low-mass dwarfs need to focus on the best selected stars to make …

To detect Earth-mass planets using the Doppler method, a major obstacle is to differentiate
the planetary signal from intrinsic stellar variability (eg pulsations, granulation, spots, and …
