ERRATUM: “Probing the deep end of the Milky Way with Kepler: Asteroseismic Analysis of 854 faint Red Giants misclassified as Cool Dwarfs” (2016, ApJ, 827, 50)
The polarization analysis of light is typically carried out using modulation schemes. The light of an unknown polarization state is passed through a set of...
With the use of N-body calculations, the numbers and properties of escaping stars from low-N (N= 100 and 1000) young embedded star clusters prior to gas...
ESO Very Large Telescope Optical Spectroscopy of BL Lacertae Objects. I. New Redshifts
We report redshift measurements for 12 BL Lacertae objects from a program aimed at obtaining high signal-to-noise ratio (up to ~500) optical spectroscopy of a...
ESO Very Large Telescope Optical Spectroscopy of BL Lacertae Objects. II. New Redshifts, Featureless Objects, and Classification Assessments
We report on ESO Very Large Telescope optical spectroscopy of 42 BL Lacertae objects of unknown redshift. Nuclear emission lines were observed in 12 objects...
ESPRESSO at VLT. On-sky performance and first results
Context. ESPRESSO is the new high-resolution spectrograph of ESO's Very Large Telescope (VLT). It was designed for ultra-high radial-velocity (RV) precision and...
ESPRESSO high-resolution transmission spectroscopy of WASP-76 b
Aims: We report on ESPRESSO high-resolution transmission spectroscopic observations of two primary transits of the highly irradiated, ultra-hot Jupiter-sized...
ESPRESSO highlights the binary nature of the ultra-metal-poor giant HE 0107-5240
Context. The vast majority of the known stars of ultra low metallicity ([Fe/H] < -4.5) are known to be enhanced in carbon, and belong to the "low-carbon band"...
