A shredded star exposes a massive black hole about 3,500 light-years from its galaxy's center

Astronomers led by Itai Sfaradi found a star torn apart by a massive black hole 1.08 kiloparsecs from its host galaxy's center. The team estimates its mass at roughly 1 million to 10 million suns and weighs two explanations for the offset.

MIT astronomers find a star slowly stripping a brown dwarf 300 light-years away

MIT-led astronomers found a star about 300 light-years away slowly pulling material off a brown dwarf companion, a process that could last billions of years. One detection shows slow stripping happens, and working out how common it is will need a larger sample of such pairs.

Small star 300 light-years away is slowly eating a brown dwarf on an 87-minute orbit

Astronomers have watched a low-mass star strip a brown dwarf for the first time, in ZTF J0440+2325 about 300 light-years away, space.com reported. The pace is slow enough for the feeding to last up to billions of years.

A borderline X-ray blip, a magnetar, and the case for watching in soft X-rays

Einstein Probe's fourth X-ray-flash supernova was too faint to confirm on its own. A wide-field optical survey looking at the same sky made it a data point.

The Whippet: a black hole shredded a massive star, and fast helium turned up months later

Astronomers report helium moving unexpectedly fast long after AT2024wpp peaked, which they read as surviving stellar structure. That complicates the tidy version of tidal disruption.
