Early-Time Observations of SN 2023wrk: A Luminous Type Ia Supernova with Significant Unburned Carbon in the Outer Ejecta
Jialian Liu, Xiaofeng Wang, Cristina Andrade +44
We present extensive photometric and spectroscopic observations of the nearby Type Ia supernova (SN) 2023wrk at a distance of about 40 Mpc. The earliest detection of this SN can be…
Ready for O4 II: GRANDMA Observations of Swift GRBs during eight-weeks of Spring 2022
I. Tosta e Melo, J. -G. Ducoin, Z. Vidadi +106
We present a campaign designed to train the GRANDMA network and its infrastructure to follow up on transient alerts and detect their early afterglows. In preparation for O4 II camp…
GRANDMA and HXMT Observations of GRB 221009A -- the Standard-Luminosity Afterglow of a Hyper-Luminous Gamma-Ray Burst
D. A. Kann, S. Agayeva, V. Aivazyan +113
GRB 221009A is the brightest Gamma-Ray Burst (GRB) detected in more than 50 years of study. In this paper, we present observations in the X-ray and optical domains after the GRB ob…
GRANDMA Observations of ZTF/Fink Transients during Summer 2021
V. Aivazyan, M. Almualla, S. Antier +80
We present our follow-up observations with GRANDMA of transient sources revealed by the Zwicky Transient Facility (ZTF). Over a period of six months, all ZTF triggers were examined…
Photometric analysis of three totally eclipsing W UMa stars with increasing periods: TYC 3700-1384-1, V1511 Her and V1179 Her
Eric Broens
The first multi-colour light curve models and period studies for the totally eclipsing W UMa stars TYC 3700-1384-1, V1511 Her and V1179 Her are presented. All three stars are A-sub…
Light curve analysis and orbital period change of the extreme mass-ratio overcontact binary AW CrB
Eric Broens
Extreme mass-ratio contact binaries with a high degree of overcontact may be in the late evolutionary stages of the contact phase. Detailed photometric analyses and orbital period…
The Unique Frequency Spectrum of the Blazhko RRc Star LS Her
Patrick Wils, Stelios Kleidis, Eric Broens
The Blazhko effect in RR Lyrae stars is still poorly understood theoretically. Stars with multiple Blazhko periods or in which the Blazhko effect itself varies are particularly cha…
