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…
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.…
No Conclusive Evidence for Transits of Proxima b in MOST photometry
David M. Kipping, Chris Cameron, Joel D. Hartman +21
The analysis of Proxima Centauri's radial velocities recently led Anglada-Escudé et al. (2016) to claim the presence of a low mass planet orbiting the Sun's nearest star once every…
Stable and unstable accretion in the classical T Tauri stars IM Lup and RU Lup as observed by MOST
Michal Siwak, Waldemar Ogloza, Slavek M. Rucinski +8
Results of the time variability monitoring of the two classical T Tauri stars, RU Lup and IM Lup, are presented. Three photometric data sets were utilised: (1) simultaneous (same f…
Spectroscopy, MOST Photometry, and Interferometry of MWC 314: Is it an LBV or an interacting binary?
Noel D. Richardson, Anthony F. J. Moffat, Raphaël Maltais-Tariant +34
MWC 314 is a bright candidate luminous blue variable that resides in a fairly close binary system, with an orbital period of 60.7530.003 d. We observed MWC 314 with a combinat…
