Spectrum of the secondary component and new orbital elements of the massive triple star Delta Ori A

A. Oplištilová, P. Mayer, P. Harmanec +13

Orionis is the closest massive multiple stellar system and one of the brightest members of the Orion OB association. The primary (Aa1) is a unique evolved O star. In this work,…

The orbital kinematics of eta Carinae over three periastra with a possible detection of the elusive secondary's motion

Emily Strawn, Noel D. Richardson, Anthony F. J. Moffat +14

The binary eta Carinae is the closest example of a very massive star, which may have formed through a merger during its Great Eruption in the mid-nineteenth century. We aimed to co…

Five years of BRITE-Constellation photometry of the luminous blue variable P Cygni: properties of the stochastic low-frequency variability

Ashley Elliott, Noel D. Richardson, Herbert Pablo +9

Luminous Blue Variables (LBVs) are massive stars that are likely to be a transitionary phase between O stars and hydrogen-free classical Wolf-Rayet stars. The variability of these…

Outbursts and stellar properties of the classical Be star HD 6226

Noel D. Richardson, Olivier Thizy, Jon E. Bjorkman +58

The bright and understudied classical Be star HD 6226 has exhibited multiple outbursts in the last several years during which the star grew a viscous decretion disk. We analyze 659…

Space Photometry with BRITE-Constellation

Weiss W. W, Zwintz K., Kuschnig R. +16

BRITE-Constellation is devoted to high-precision optical photometric monitoring of bright stars, distributed all over the Milky Way, in red and/or blue passbands. Photometry from s…

BRITE observations of Centauri and Lupi, the first non-eclipsing members of the new class of nascent binaries

M. Jerzykiewicz, A. Pigulski, G. Michalska +8

Results of an analysis of the BRITE-Constellation and SMEI photometry and radial-velocity observations, archival and new, of two single-lined spectroscopic binary systems Centa…
