Evolution of brightness and magnetic features of young solar-type stars – II. The young F8 star HIP 71933 [PDF]
, 2023 The early, active history of our Sun is still not fully understood. Observations of the magnetic fields on active young solar-type stars allow us an insight into the early evolution of our Sun.

Gravity darkening in late-type stars [PDF]
Astronomy & Astrophysics, 2018 Context.Recent interferometric data have been used to constrain the brightness distribution at the surface of nearby stars, in particular the so-called gravity darkening that makes fast rotating stars brighter at their poles than at their equator. However, good models of gravity darkening are missing for stars that posses a convective envelope.Aim.In ...

Late-type stars found in the FBS. New carbon stars [PDF]
, 2008 We present new observations of seven late-type stars previously discovered in the First Byurakan Survey (FBS). These observations prove that they belong to the family of carbon (C) stars. Seventy-nine similar FBS C stars were previously known.

A Spectroscopic Orbit for the Late-type Be Star β CMi [PDF]
The Astrophysical Journal, 2017 Abstract The late-type Be star β CMi is remarkably stable compared to other Be stars that have been studied. This has led to a realistic model of the outflowing Be disk by Klement et al. These results showed that the disk is likely truncated at a finite radius from the star, which Klement et al.

The Wolf-Rayet stars in M31 I. Analysis of the late-type WN stars [PDF]
, 2014 Context. Comprehensive studies of Wolf-Rayet stars were performed in the past for the Galactic and the LMC population. The results revealed significant differences, but also unexpected similarities between the WR populations of these different galaxies ...

Progress on the calibration of surface brightness–color relations for early- and late-type stars [PDF]
, 2021 International audienceContext. Surface brightness-color relations (SBCRs) are widely used for estimating angular diameters and deriving stellar properties. They are critical to derive extragalactic distances of early-type and late-type eclipsing binaries

Late B-type stars and their candidate companions resolved with [PDF]
, 2003 We present the first results from a series of Chandra observations carried out with the aim to examine the origin of X-ray emission in main-sequence late B-type stars.

Differential Line Shifts in Late Type Stars [PDF]
International Astronomical Union Colloquium, 1980 AbstractThe differential line shifts method for studying convective type motions has been described in the review of Glebocki and Stawikowski at this colloquium. Here the results of differential line shifts for twenty late type stars are presented. Line shifts were determined either from published wavelength measurements (α CMi, β Peg, α Boo, α Ser, α ...
