GRB 250424A: A Case Study of Energy Injection with Multiwavelength Observations

Yifang Liang, Yun Wang, WeiKang Zheng +61

We present a comprehensive multiwavelength analysis of the long-duration gamma-ray burst (GRB) 250424A. Our dataset spans from the prompt gamma-ray emission to late-time optical mo…

The Physics of Mass Transfer in Substellar and Low-Mass Binaries

Samuel Whitebook, Jim Fuller, Kevin Burdge +3

Several dozen binary ultracool and brown dwarf systems have been identified to date. These systems represent valuable probes of star and planet formation at the lowest mass scales.…

Stars stably accreting from substellar objects

Aaron Householder, Kaitlyn Shin, Kevin B. Burdge +11

Substellar objects such as brown dwarfs and planets are generally expected to remain detached from their main-sequence host stars unless orbital decay or stellar expansion brings t…

A Mass Transferring Brown Dwarf Binary on a 57 Minute Orbit

Samuel Whitebook, Antonio C. Rodriguez, Kevin Burdge +9

Mass transfer in stellar binaries has been well studied in most stellar mass ranges, with the notable exception of ultracool stars and substellar brown dwarfs. We report the discov…

Optical Spectroscopy of the Most Compact Accreting Binary Harboring a Magnetic White Dwarf and a Hydrogen-rich Donor

Ilkham Galiullin, Antonio C. Rodriguez, Kareem El-Badry +4

Accreting white dwarfs in close binary systems, commonly known as cataclysmic variables (CVs), with orbital periods below the canonical period minimum ( 80 minutes) are ra…

The Local Galactic Transient Survey Applied to an Optical Search for Directed Intelligence

Alex Thomas, Natalie LeBaron, Luca Angeleri +26

We discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrest…
