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…
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…
Bright Long Secondary Period Stars for Follow-up Observations
P. Iwanek, D. M. Skowron, G. Pojmański +1
Long secondary period (LSP) variable stars are a subclass of long-period variables (LPV) that exhibit additional long-term variability alongside pulsations. Despite being observed…
ASASSN-24fw: Candidate circumplanetary disk occultation of a main-sequence star
Nadia L. Zakamska, Gautham Adamane Pallathadka, Dmitry Bizyaev +24
Dusty disks around planetary and substellar companions in outer reaches of exo-planetary systems can be detected as long-lasting occultations, provided the observer is close to the…
K2 Discovery of a Circumsecondary Disk Transiting EPIC 220208795
L. van der Kamp, D. M. van Dam, M. A. Kenworthy +2
Observations of the star EPIC 220208795 (2MASS J01105556+0018507) reveal a single, deep and asymmetric eclipse, which we hypothesize is due to an eclipsing companion surrounded by…
