Using binary statistics in Taurus-Auriga to distinguish between brown dwarf formation processes

. Aims. For young stars in Taurus-Auriga the binary fraction has been shown dynamically in which the binary fraction is large for stars down to M-dwarfs and small in the Taurus-Auriga star-forming region. ...

Shaking the Pot of Modelling Tools: Some Open Problems in the Field

To inspire and provoke lively discussions, I argue that the accuracy of the basic physical properties of stars, based on analyses of well-observed detached binaries, might be worse than usually believed. I offer some ways how to dea...

Binary stars with RR Lyrae components - new candidates in the Galactic bulge

There is a significant lack of binary stars with RR Lyrae components. In this brief contribution, we introduce 20 new candidates in the Galactic bulge identified on the basis of the Light-Travel-Time Effect with expected orbital per...

HD 161306: a radiatively interacting Be binary?

suggests that the star is a binary similar to phi Per, 59 Cyg, or FY CMa, i.e. a radiativelv interacting Be binary - a rare case among Be stars. This type of object is also called a phi Per-type binary or...
