A BVRcIc Survey of W Ursae Majoris Binaries

, 2012
We report on a BVRcIc survey of field W Ursae Majoris binary stars and present accurate colors for 606 systems that have been observed on at least three photometric nights from a robotic observatory in southern Arizona. Comparison with earlier photometry

An All-sky 3D Dust Map Based on Gaia and LAMOST

The Astrophysical Journal Supplement Series
We present a comprehensive 3D dust-reddening map covering the entire Milky Way, constructed by combining reddening estimates based on Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST) low-resolution spectra ( E ( B  −  V ) _LAMOST ) with ...

HIGH PRECISION EFFECTIVE TEMPERATURES OF F-K SUPERGIANTS AND CLASSICAL CEPHEIDS

Odessa Astronomical Publications, 2017
We present precise effective temperatures (Teff) of 110 F-K supergiants determined from the method of line depth ratios. For each star, we have measured the line depths a large number of spectral lines of low and high excitation potentials and ...

MODELS OF ENERGY DISTRIBUTION IN SPECTRUM OF SAKURAFS OBJECT

Odessa Astronomical Publications, 2017
Theoretical energy distributions in a spectrum of Sakurai's object (SO) are calculated for a grid of hydrogen-deficient and carbon-rich model atmospheres of Teff = 5000-6200 K and log g= 0.0-1.0.
