The Gaia-ESO Survey: Projected Rotational Velocities of B stars in the Carina Nebula
W. Santos, S. Daflon, J. V. Sales Silva +19
The Carina Nebula is an active star-forming region with several open clusters rich in massive OB stars, thus making it an optimal target for studying stellar properties such as rot…
Extreme photometric and polarimetric variability of blazar S4 0954+65 at its maximum optical and -ray brightness levels
C. M. Raiteri, M. Villata, M. I. Carnerero +64
In 2022 the BL Lac object S4 0954+65 underwent a major variability phase, reaching its historical maximum brightness in the optical and -ray bands. We present optical photometri…
Discovery of a Highly Polarized Optical Microflare in the Blazar S5 0716+714 During 2014 WEBT Campaign
Gopal Bhatta, Arti Goyal, Michal Ostrowski +42
The occurrence of low-amplitude flux variations in blazars on hourly timescales, commonly known as microvariability, is still a widely debated subject in high-energy astrophysics.…
The Gaia-ESO Survey: Catalogue of H emission stars
Gregor Traven, Tomaž Zwitter, Sophie Van Eck +18
We discuss the properties of H emission stars across the sample of 22035 spectra from the Gaia-ESO Survey internal data release, observed with the GIRAFFE instrument and largely…
