Spectroscopic observations of flares and superflares on AU Mic
P. Odert, M. Leitzinger, R. Greimel +13
The young active flare star AU~Mic is the planet host star with the highest flare rate from TESS data. Therefore, it represents an ideal target for dedicated ground-based monitorin…
Mass ratio of single-line spectroscopic binaries with visual orbits using Bayesian inference and suitable priors
Jennifer Anguita-Aguero, Rene A. Mendez, Miguel Videla +4
We present orbital elements for twenty-two single-line binaries, nine of them studied for the first time, determined from a joint spectroscopic and astrometric solution. The astrom…
A new look into putative duplicity and pulsations of the Be star CMi
P. Harmanec, M. Svanda, D. Korcakova +6
Bright Be star beta CMi has been identified as a non-radial pulsator on the basis of space photometry with the MOST satellite and also as a single-line spectroscopic binary with a…
Beryllium detection in the very fast nova ASASSN-16kt (V407 Lupi)
L. Izzo, P. Molaro, P. Bonifacio +8
We present high-resolution spectroscopic observations of the fast nova ASASSN-16kt (V407 Lup). A close inspection of spectra obtained at early stages has revealed the presence of l…
Ori and Lib: Two new massive heartbeat binaries
Andrzej Pigulski, Monika K. Kaminska, Krzysztof Kaminski +28
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow e…
Stellar parameters and H line profile variability of Be stars in the BeSOS survey
C. Arcos, S. Kanaan, J. Chávez +3
The Be phenomenon is present in about 20 of the B-type stars. Be stars show variability on a broad range of timescales, which in most cases is related to the presence of a circ…
