Long-term optical variability of high-mass X-ray binaries. III. Polarimetry
P. Reig, D. Blinov, A. Tzouvanou
Be/X-ray binaries are the most numerous group of high-mass X-ray binaries. Their long-term optical and infrared variability reflects the evolution of the circumstellar disk around…
The Demographics of Binary Companions to Stripped-Envelope Supernovae: Confronting Observations with Population Synthesis
E. Zapartas, O. D. Fox, J. Su +15
Stripped-envelope supernovae (SESNe) mark the deaths of massive stars without hydrogen-rich envelopes. Most SESNe likely originate from binary systems where a companion stripped th…
Populations of evolved massive binary stars in the Small Magellanic Cloud II: Predictions from rapid binary evolution
C. Schürmann, X. -T. Xu, N. Langer +10
Massive star evolution plays a crucial role in astrophysics but bares large uncertainties. This problem becomes more severe by the majority of massive stars being born in close bin…
Fast optical variability in Supergiant X-ray binaries
D. Di Filippantonio, P. Reig, J. Fabregat
The main goal of this work is to investigate the fast photometric variability of the optical counterparts to supergiant X-ray binaries and to compare the general patterns of such v…
Emulators for stellar profiles in binary population modeling

Knowledge about the internal physical structure of stars is crucial to understanding their evolution. The novel binary population synthesis code POSYDON includes a module for inter…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
Zero-polarization candidate regions for calibration of wide-field optical polarimeters
N. Mandarakas, G. V. Panopoulou, V. Pelgrims +14
Context. Calibration of optical polarimeters relies on the use of stars with negligible polarization (unpolarized standard stars) for determining the instrumental polarization zero…
Evolved Massive Stars at Low-metallicity V. Mass-Loss Rate of Red Supergiant Stars in the Small Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +17
We assemble the most complete and clean red supergiant (RSG) sample (2,121 targets) so far in the Small Magellanic Cloud (SMC) with 53 different bands of data to study the MLR of R…
Fast time optical variability in Be/X-ray binaries. Pulsation and rotation
P. Reig, J. Fabregat
Classical Be stars, regardless of spectral subtype, display multiperiodic light modulations in the frequency range 0.1-12 d, when observed with high-cadence and long duratio…
A synthetic population of Wolf-Rayet stars in the LMC based on detailed single and binary star evolution models
D. Pauli, N. Langer, D. R. Aguilera-Dena +2
Without doubt, mass transfer in close binary systems contributes to the populations of Wolf-Rayet (WR) stars in the Milky Way and the Magellanic Clouds. However, the binary formati…
Multiwavelength observations of Swift J0243.6+6124 from 2017 to 2022
Wei Liu, Jingzhi Yan, Pablo Reig +8
We have obtained optical spectroscopy and photometry data during four years after the event. The long-term photometric light-curve and the equivalent widths of the Halpha and He I…
The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
Mergers prompted by dynamics in compact, multiple-star systems: a stellar-reduction case for the massive triple TIC 470710327
Alejandro Vigna-Gómez, Bin Liu, David R. Aguilera-Dena +3
TIC 470710327, a massive compact hierarchical triple-star system, was recently identified by NASA's Transiting Exoplanet Survey Satellite (TESS). TIC 470710327 is comprised of a co…
Stripped-envelope stars in different metallicity environments. II. Type I supernovae and compact remnants
David R. Aguilera-Dena, Bernhard Müller, John Antoniadis +4
Stripped-envelope stars can be observed as Wolf-Rayet (WR) stars, or as less luminous hydrogen-poor stars with low mass loss rates and transparent winds. Both types are potential p…
A machine-learning photometric classifier for massive stars in nearby galaxies I. The method
Grigoris Maravelias, Alceste Z. Bonanos, Frank Tramper +3
(abridged) Mass loss is a key parameter in the evolution of massive stars, with discrepancies between theory and observations and with unknown importance of the episodic mass loss.…
Revisiting the evolved hypergiants in the Magellanic Clouds
Michalis Kourniotis, Michaela Kraus, Olga Maryeva +2
The massive stars that survive the phase of red supergiants (RSGs) spend the rest of their life in extremity. Their unstable atmospheres facilitate the formation and episodic eject…
