Insights into the inner regions of the FU Orionis disc
Michal Siwak, Maciej Winiarski, Waldemar Ogloza +12
Context. We investigate small-amplitude light variations in FU Ori occurring in timescales of days and weeks. Aims. We seek to determine the mechanisms that lead to these light cha…
Photometric variability of TW~Hya from seconds to years as seen from space and the ground in 2013-2017
M. Siwak, W. Ogloza, A. F. J. Moffat +9
This is the final photometric study of TW Hya based on new MOST satellite observations. During 2014 and 2017 the light curves showed stable 3.75 and 3.69 d quasi-periodic oscillati…
Physical parameters and 0.2% parallax of the detached eclipsing binary V923 Scorpii
T. Pribulla, A. Mérand, P. Kervella +10
V923 Sco is a bright ( = 5.91), nearby ( = 15.460.40 mas) southern eclipsing binary. Because both components are slow rotators, the minimum masses of the components are…
The MOST view of Cepheids
L. Molnár, A. Derekas, R. Szabó +6
The MOST space telescope observed four Cepheid variables so far, all of different subtypes. Here we summarize the results obtained and the possible ways to continue to study these…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
MOST Observations of our Nearest Neighbor: Flares on Proxima Centauri
James R. A. Davenport, David M. Kipping, Dimitar Sasselov +2
We present a study of white light flares from the active M5.5 dwarf Proxima Centauri using the Canadian microsatellite MOST. Using 37.6 days of monitoring data from 2014 and 2015,…
