A near-IR survey is conducted in order to penetrate the dust of the Galactic plane through the K window and study the flux from Rayleigh-Jeans tail emission in...

The authors present optical and near infrared photometry, covering from 0.36 to 2.3 microns, for a wide sample of red giant stars in the globular cluster M3...

Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure...

Approximate carbon abundances and C-12/C-13 isotope ratios are obtained for 70 M giant stars from intermediate-resolution spectrophotometry of the CO bands near...

The authors have used high resolution IUE spectra from their own studies and from the archive to examine the Mg II h and k chromospheric emission cores of a...

We report the results of a systematic study on the spatial variation of the electron density in a selected group of bright giant H II complexes in the galaxies...

A study of IUE spectra of eight cool G4-K0 giants shows evidence of interstellar Mg II absorption in all the stars but Delta Dra. Sharp features are detected in...
