Low-power jet-interstellar medium interaction in NGC 7319 revealed by JWST/MIRI MRS
We present JWST/MIRI MRS spectroscopy of NGC 7319, the largest galaxy in the Stephan's Quintet, observed as part of the Early Release Observations (ERO). NGC...
Low-Resolution Maps of Comet p/ Halley in Principal Atomic and Molecular Species
The authors present maps of a 3arcmin×2arcmin region of the inner coma of comet P/Halley, at 10arcsec resolution, in CN (3883 Å); C2 (5100 Å); C3 (4040 Å); CN...
Low-resolution spectroscopy and spectral energy distributions of selected sources towards σ Orionis
Aims: We study in detail nine sources in the direction of the young σ Orionis cluster, which is considered to be a unique site for studying stellar and...
Low-resolution spectroscopy of main sequence stars belonging to 12 Galactic globular clusters. I. CH and CN band strength variations
Context. Globular clusters show star-to-star abundance variations for light elements that are not yet well understood. The preferred explanation involves a self...
Lower atmosphere and pressure evolution on Pluto from ground-based stellar occultations, 1988-2016
Context. The tenuous nitrogen (N2) atmosphere on Pluto undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has recently (July...
Lower-than-expected flare temperatures for TRAPPIST-1
Aims: Stellar flares emit thermal and nonthermal radiation in the X-ray and ultraviolet (UV) regime. Although high energetic radiation from flares is a...
Context: The knowledge of the binary properties of metal-poor and solar-metallicity stars can shed light on the potential differences between the formation...
Lucky spectroscopy, an equivalent technique to lucky imaging. II. Spatially resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
Context. Many massive stars have nearby companions. These hamper a characterization of massive stars through spectroscopy. Aims: We continue to obtain spatially...
