Optical observations on the young Type Ia SN 2021fxy with detached high velocity features
Liping Li, Jujia Zhang, Zhenyu Wang +5
We present optical observations on the young type Ia supernova (SN Ia) SN 2021fxy obtained within a few days after the explosion, with a focus on its prominent high-velocity featur…
The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve
Y. -Z. Cai, A. Pastorello, R. Chiba +65
We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…
Ellipsoidal modulation and multi-wavelength activity in the pre-cataclysmic binary RX J1553.0+4457
S. -Y. Wu, M. Gritsevich, Q. -H. Lao +39
RX J1553.0+4457 (TMTS J15530469+4457458) is a detached post-common-envelope binary containing a cool white dwarf and an active late-type companion. We present a multi-wavelength st…
SN 2022acko: a low-luminosity SNe IIP with signs of early circumstellar interaction
Lin Han, Zhang Jujia, Wang Xiaofeng +13
We present optical-ultraviolet photometry and optical spectra for the type II supernova (SN) 2022acko. The spectroscopic observations span phases from 1.5 to 60 days…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, K. Maeda +63
We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…
SN 2024gy: Multi-epoch Spectroscopic Features Suggestive of Delayed Detonation in a Type Ia Supernova
Liping Li, Zhenyu Wang, Jialian Liu +28
We present photometric and spectroscopic observations of SN 2024gy, a Type Ia supernova (SN Ia) exhibiting high-velocity features (HVFs) in its early-time spectra. This SN reaches…
A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
Circumstellar Material Ejected Violently by A Massive Star Immediately before its Death
Jujia Zhang, Han Lin, Xiaofeng Wang +7
Type II supernovae represent the most common stellar explosions in the Universe, for which the final stage evolution of their hydrogen-rich massive progenitors towards core-collaps…
Grandma: a network to coordinate them all
S. Agayeva, S. Alishov, S. Antier +75
GRANDMA is an international project that coordinates telescope observations of transient sources with large localization uncertainties. Such sources include gravitational wave even…
