Eppur binaria non è esclusa: Pulsations in CZ Tuc appear to be tidally excited by its veiled companion
Piotr A. Kołaczek-Szymański, Patryk Iwanek, Jim Fuller +3
Long secondary periods (LSPs), observed in about one-third of pulsating red giants, remain unexplained despite decades of study, with binarity and non-radial oscillations as the le…
Multiplicity of Cool Stars and their Evolution
Matthew I. Swayne, Leen Decin, Theo Khouri +12
Making up a sizeable portion of the galactic census, stellar multiples are experiencing a renaissance. Enabling the study of multiple strands of the study of cool stars, stellar mu…
Incorporating physical source parameters into microlensing modeling
Mateusz J. Mróz, Radosław Poleski, Andrzej Udalski +14
Modeling of complex microlensing events suffers from many difficult-to-disentangle degeneracies. This is especially the case for orbital motion of the source in a binary system, th…
Eppur binaria non é esclusa: Gaia astrometry does not disfavor a binary origin for Long Secondary Periods
Patryk Iwanek, Piotr A. Kołaczek-Szymański, Dorota M. Skowron +2
We present an independent reassessment of the nearby long secondary period (LSP) stars analyzed by Shariat et al. (2026). By inspecting long-term All Sky Automated Survey (ASAS) li…
Thirty Circumbinary Disk Occultation Systems (KH 15D-like stars) from the OGLE Project
M. A. Urbanowicz, I. Soszyński, P. Pietrukowicz +14
We present a catalog of 30 stars that are candidates for KH 15D-like binary systems, in which the observed brightness variations are caused by a circumbinary dusty disk that period…
The Role of Long Period Variable Stars in Observational Astrophysics
Dorota M. Skowron, Igor Soszyński
Long-period variables (LPVs) are evolved red giant and supergiant stars whose pulsations provide unique insights into late stages of stellar evolution and serve as essential tools…
