Context. The small radius and high density of CoRoT-7b implies that this transiting planet belongs to a different species than all transiting planets previously...
Convective line shifts for the Gaia RVS from the CIFIST 3D model atmosphere grid
Context. To derive space velocities of stars along the line of sight from wavelength shifts in stellar spectra requires accounting for a number of second-order...
Convective Wavelength Shifts in the Spectra of Late-Type Stars
We present ultrahigh-resolution spectra for a set of nearby F-G-K stars on, or close to, the main sequence. The wavelength shifts of stellar lines relative to...
Convectively Driven Sinks and Magnetic Fields in the Quiet-Sun
We study the relation between mesogranular flows, convectively driven sinks and magnetic fields using high spatial resolution spectropolarimetric data acquired...
Doppler velocities in the penumbra of a δ-configuration sunspot observed near the limb indicate flows that converge upon the line separating locally positive...
Cool and data-driven: an exploration of optical cool dwarf chemistry with both data-driven and physical models
Detailed chemical studies of F/G/K - or solar-type - stars have long been routine in stellar astrophysics, enabling studies in both Galactic chemodynamics and...
Cool White Dwarfs Found in the UKIRT Infrared Deep Sky Survey
We present the results of a search for cool white dwarfs in the United Kingdom InfraRed Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Large Area Survey...
Cool White Dwarfs Identified in the Second Data Release of the UKIRT Infrared Deep Sky Survey
We have paired the second data release of the Large Area Survey of the UKIRT Infrared Deep Sky Survey with the fifth data release of the Sloan Digital Sky...
Coronal line forest AGN - II. Analysis of the spectral energy distribution
Coronal-Line Forest Active Galactic Nuclei (CLiF AGN) are characterized by strong, high-ionization lines, which are in contrast to what is found in typical AGNs...
