SN 2024iss: A Double-peaked Type IIb Supernova with Evidence of Circumstellar Interaction
Liyang Chen, Xiaofeng Wang, Qinyu Wu +54
We present optical, ultraviolet, and X-ray observations of supernova (SN) 2024iss, a Type IIb SN that shows a prominent double-peaked light curve. We modeled the first peak with a…

A post-common-envelope binary with double-peaked Balmer emission lines from TMTS
Qichun Liu, Xiaofeng Wang, Jie Lin +20
The dynamical method provides an efficient way to discover post-common-envelope binaries (PCEB) with faint white dwarfs (WDs), thanks to the development of time-domain survey proje…

Investigating the Period-Luminosity Relations of delta Scuti Stars: A Pathway to Distance and 3-D Dust Map Inference
Fangzhou Guo, Joshua S. Bloom, Xiaofeng Wang +12
While delta Scuti stars are the most numerous class of kappa-mechanism pulsators in the instability strip, the short periods and small peak-to-peak amplitudes have left them unders…
