We combine high-resolution spectroscopic data from APOGEE-2 survey Data Release 16
(DR16) with broad-band photometric data from several sources as well as parallaxes from …

Ensemble studies of red-giant stars with exquisite asteroseismic (Kepler), spectroscopic
(APOGEE), and astrometric (Gaia) constraints offer a novel opportunity to recast and …

The distribution of close-in exoplanets is shaped by a complex interplay between
atmospheric and dynamical processes. The Desert-Rim Exoplanets Atmosphere and …

Context. The population of close-in exoplanets features a desert of hot Neptunes whose
origin remains uncertain. These planets may have lost their atmosphere, eroding into mini …

We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), α-
element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant stars …

Stellar ages are a crucial component to studying the evolution of the Milky Way. Using Gaia
DR2 distance estimates, it is now possible to estimate stellar ages for a larger volume of …

Context. It is well known that the magnetic activity of solar-type stars decreases with age, but
it is widely debated in the literature whether there is a smooth decline or if there is an early …

We present a combination of the Schwarzschild orbit-superposition dynamical modelling
technique with the spatially resolved mean stellar age and metallicity maps to uncover the …

Context. Thanks to ongoing efforts to compute accurate stellar ages, we are able to
characterise stars in different regions of the Milky Way. The Gaia and Kepler space …

In order to assess the impact of the environment on the formation and evolution of galaxies,
accurate assembly histories of such galaxies are needed. However, these measurements …
