Researchers show that the properties of a supernova’s host galaxy can be a valuable tool for classifying the explosion, especially when combined with a redshift value.
The discovery of 29 stars with properties similar to the enigmatic ASASSN-16oh suggests the existence of a class of white dwarfs with optical emission 1,000 fainter than classical novae.
Using a laboratory vacuum setup and a strong electric field, researchers have investigated the electrification of dust grains, helping to understand how dust is freed from the Martian surface.
Magnetohydrodynamic simulations of stellar interiors find unexpected behavior in stellar magnetic fields at the convective–radiative boundary, which has consequences for asteroseismology.
The Imaging X-ray Polarimetry Explorer has made yet another first polarization measurement of an object, finding a low polarization degree that could be attributed to scattering.
New radio observations of a binary system containing a pulsar and a massive companion star reveal the interaction between the pulsar wind and the companion star’s wind or disk.
