High-mass companions can widen common-envelope outcomes in giant stars
—
in AstrophysicsWhat the study found The study found that higher companion mass ratios can produce wider orbits after a common-envelope event, which is an episode where two stars share a single outer envelope. Even so, the widest separation predicted here was still only about 50 solar radii, smaller than the observed range. Why the authors say…
BAGLE adds binary lens and source models for microlensing
—
in AstrophysicsWhat the study found The BAGLE Python software package now includes models for binary sources and binary lenses in gravitational microlensing. These models include Keplerian orbits, as well as simpler descriptions of orbital motion such as acceleration, linear, or stationary motion of the secondary companion. Why the authors say this matters The authors say these…
Magnetic charge changes orbits and waveforms near regular black holes
—
in AstrophysicsStudy explores how magnetic charge in regular black holes alters gravitational waveforms from periodic orbits, offering new constraints on black hole properties through gravitational wave.
