TIC 366240660 - A Dynamically Active Triple With a Very Short Outer Period of 30.5 Days
S. A. Rappaport, T. Borkovits, G. Torres +17
Methods: We analyze TESS photometric data, radial velocity measurements, and eclipse timing variation curves for the triple star system, TIC 366240660, with a photodynamical code t…
The Eye of Sauron in SN 2025ngs: a Short-plateau Cousin of SN 1998S with Evidence for a Ring-like Circumstellar Medium
Conor L. Ransome, David J. Sand, K. Azalee Bostroem +35
Interacting supernovae probe the twilight years of massive stars, exhibiting signatures of interaction between the supernova ejecta and surrounding material expelled from the proge…
SN 2023ixf in M101: physical parameters from bolometric light curve modeling
J. Vinko, Zs. R. Bodola, A. Godeny +25
We present new photometric observations of the core-collapse supernova SN 2023ixf occurred in M101, taken with the RC80 and BRC80 robotic telescopes in Hungary. The initial nickel…
Seven new triply eclipsing triple star systems
S. A. Rappaport, T. Borkovits, T. Mitnyan +19
We have identified nearly a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. These systems are noteworthy in that we c…
SN 2021gno: a Calcium-rich transient with double-peaked light curves
K. Ertini, G. Folatelli, L. Martinez +52
We present extensive ultraviolet (UV) and optical photometric and optical spectroscopic follow-up of supernova (SN)~2021gno by the "Precision Observations of Infant Supernova Explo…
SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
BU Canis Minoris -- the Most Compact Known Flat Doubly Eclipsing Quadruple System
Theodor Pribulla, Tamás Borkovits, Rahul Jayaraman +25
We have found that the 2+2 quadruple star system BU CMi is currently the most compact quadruple system known, with an extremely short outer period of only 121 days. The previous re…
A Study of Nine Triply Eclipsing Triples
S. A. Rappaport, T. Borkovits, R. Gagliano +22
In this work we report the independent discovery and analysis of nine new compact triply eclipsing triple star systems found with the TESS mission: TICs 47151245, 81525800, 9901326…
Six New Compact Triply Eclipsing Triples Found With TESS
S. A. Rappaport, T. Borkovits, R. Gagliano +21
In this work we report the discovery and analysis of six new compact triply eclipsing triple star systems found with the TESS mission: TICs 37743815, 42565581, 54060695, 178010808,…
The compact multiple system HIP 41431
T. Borkovits, J. Sperauskas, A. Tokovinin +4
The nearby (50 pc) K7V dwarf HIP~41431 (EPIC 212096658) is a compact 3-tier hierarchy. Three K7V stars with similar masses, from 0.61 to 0.63 solar, make a triple-lined spectroscop…
Eclipsing Spotted Giant Star With K2 and Historical Photometry
K. Oláh, S. Rappaport, T. Borkovits +15
Context. Stars can maintain their observable magnetic activity from the PMS to the tip of the red giant branch. However, the number of known active giants is much lower than active…
Variability of M giant stars based on Kepler photometry: general characteristics
E. Bányai, L. L. Kiss, T. R. Bedding +15
M giants are among the longest-period pulsating stars which is why their studies were traditionally restricted to analyses of low-precision visual observations, and more recently,…
