The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

We provide evidence that the obliquities of stars with close-in giant planets were initially
nearly random, and that the low obliquities that are often observed are a consequence of …

We present a high-precision radial velocity (RV) survey of 719 FGKM stars, which host 164
known exoplanets and 14 newly discovered or revised exoplanets and substellar …

Context. The CARMENES exoplanet survey of M dwarfs has obtained more than 18 000
spectra of 329 nearby M dwarfs over the past five years as part of its guaranteed time …

Transmission spectra are differential measurements that utilize stellar illumination to probe
transiting exoplanet atmospheres. Any spectral difference between the illuminating light …

Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation,
and these losses can affect their physical and chemical evolution. Studies of atmospheric …

Context. The nearest stars provide a fundamental constraint for our understanding of stellar
physics and the Galaxy. The nearby sample serves as an anchor where all objects can be …

We present an update of the open-source photochemical kinetics code VULCAN to include
C–H–N–O–S networks and photochemistry. The additional new features are advection …

Ground-and space-based planet searches employing radial velocity techniques and transit
photometry have detected thousands of planet-hosting stars in the Milky Way. With so many …

The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any
orbiting planets. In this paper, we present the survey sample by publishing one CARMENES …
