There has been an incredibly large investment in obtaining high-resolution stellar spectra for
determining chemical abundances of stars. This information is crucial to answer …

Multiple codes are available to derive atmospheric parameters and individual chemical
abundances from high-resolution spectra of AFGKM stars. Almost all spectroscopists have …

Abstract We present The Payne, a general method for the precise and simultaneous
determination of numerous stellar labels from observed spectra, based on fitting physical …

AF Lep A+ b is a remarkable planetary system hosting a gas-giant planet that has the lowest
dynamical mass among directly imaged exoplanets. We present an in-depth analysis of the …

Context. The β Pictoris moving group is one of the most well-known young associations in
the solar neighbourhood and several members are known to host circumstellar discs …

Aims. We report on ESPRESSO high-resolution transmission spectroscopic observations of
two primary transits of the highly irradiated, ultra-hot Jupiter-sized planet, WASP-76b. We …

Data from the SDSS-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE-
2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14). These …

We present the detection of neutral helium at 10833 Å in the atmosphere of WASP-52b and
tentative evidence of helium in the atmosphere of the grazing WASP-177b, using high …

Giant exoplanets orbiting close to their host stars are unlikely to have formed in their present
configurations. These 'hot Jupiter'planets are instead thought to have migrated inward from …

The distribution of spin–orbit angles for systems with wide-separation, tidally detached
exoplanets offers a unique constraint on the prevalence of dynamically violent planetary …
