Turkish astronomers have analyzed the observational data of the transient X-ray pulsar MAXI J1409-619 to probe the properties of this source. The study provided a comprehensive timing and X-ray spectral analysis of the pulsar, ...
Cataclysmic variables (CVs) are binary star systems consisting of a white dwarf and a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. Although over ...
For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. This finding was observed by ESO's X-shooter spectrograph on the Very Large Telescope ...

Astronomers have detected a new slowly rotating radio pulsar as part of the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB). The newly found object, designated PSR J2251−3711, turns out to be one of the slowest ...
Using NASA's prolonged Kepler spacecraft mission, known as K2, astronomers have investigated a peculiar polar designated EU Cancri. The new observations, described in a paper published August 9 on arXiv.org, provide more ...
Polish astronomers have detected a new ultracompact X-ray binary as part of the Optical Gravitational Lensing Experiment (OGLE). The newly found binary, designated OGLE-UCXB-01, is an unusual periodic variable object with ...
Using Giant Metrewave Radio Telescope (GMRT), astronomers have observed the magnetar XTE J1810−197 after its recent radio outburst to investigate its emission. Results of the study, presented in a paper published August ...
Astronomers have reported a serendipitous discovery of a new millisecond pulsar as part of an observational campaign using the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The newly detected pulsar has ...
Researchers digging at the University of North Carolina at Charlotte's ongoing archaeological excavation on Mount Zion in Jerusalem have announced a second significant discovery from the 2019 season—clear evidence of the ...
