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 ...

A search for diffuse bands in fullerene planetary nebulae: evidence of diffuse circumstellar bands
, 2014 Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common fullerenes (C60 and C70) around some planetary nebulae (PNe) now enable us to study the DIBs ...

A Study of Interstellar Reddening at High Galactic Latitudes [PDF]
Symposium - International Astronomical Union, 1973 A series of finding lists of A stars in regions at high galactic latitudes has been published in the last few years. Strömgren four-color and Hβ measures have been made of stars in five of the regions, allowing the interstellar absorption in each to be calculated.

An All-sky 3D Dust Map Based on Gaia and LAMOST
The Astrophysical Journal Supplement SeriesWe 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 ...

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.
