By analyzing the data from the Spektr-RG (SRG) space observatory and from the Zwicky Transient Facility (ZTF), astronomers from the California Institute of Technology (Caltech) and elsewhere have discovered two new polars. ...
The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind—known as a white dwarf—is sucking in debris from both the system's inner and outer reaches, UCLA astronomers ...

By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have observed a young planetary nebula known as IC 4997. Results of the observational campaign, presented in a paper published May 12 on ...
A team of astronomers, with the help of the European Southern Observatory's Very Large Telescope (ESO's VLT), have observed a new type of stellar explosion—a micronova. These outbursts happen on the surface of certain stars, ...

Using ESA's XMM-Newton and NASA's NuSTAR spacecraft, astronomers have observed a galactic source designated IGR J18007–4146. The observational campaign has found that this source is an intermediate polar. The finding is ...
Using the 4.1-meter SOAR Telescope in Chile, astronomers have discovered the first example of a binary system where a star in the process of becoming a white dwarf is orbiting a neutron star that has just finished turning ...

An international team of astronomers has performed multi-epoch optical and near-infrared observations of a slow nova known as V2891 Cygni. Results of the study, published December 26 on the arXiv pre-print repository, deliver ...
German astronomers have conducted photometric observations of a recently discovered polar known as J1832.4-1627. This object is the first deeply eclipsing stream-fed intermediate polar so far detected. The study was detailed ...
