Interacting Binary Star Environments and the W Ser - DPV - Algol Connection

TL;DR

This paper reviews various types of interacting binary stars, highlighting an evolutionary sequence from W Serpentids to Algols, emphasizing the role of mass transfer rates in their observable properties and mass loss behaviors.

Contribution

It proposes a potential evolutionary sequence linking W Serpentids, DPVs, and Algols, emphasizing the importance of mass transfer rates in their development.

Findings

W Serpentids are very massive with irregular variability.

DPVs are less massive with regular, cyclic mass loss.

The sequence suggests an evolution driven by changing mass transfer rates.

Abstract

Recent work on some kinds of interacting binaries is summarized, with emphasis on Cataclysmic Variables, Algol-like variables and the recently discovered Double Periodic Variables (DPVs). The sequence W Serpentids (very massive with irregular variability and large mass loss) $\to$ DPVs (less massive with regular variability and ciclic mass loss) $\to$ Algols (even less massive with small mass loss) could correspond to an evolutionary sequence, and illustrate the importance of the mass transfer rate in shaping observable and mass loss properties for these systems.
