Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting ...
Astronomers from India have reported the finding of a companion star to an intermediate-mass Herbig Ae star known as V1787 Ori. The newly detected object turns out to be of M-type and is about 60% less massive than our sun. ...
Massive stars end their lives with energetic explosions known as supernovae. Stripped-envelope supernovae show weak or no traces of hydrogen in their ejecta, meaning that the star loses most or all of its hydrogen-rich outer ...

Using various space observatories, Italian astronomers have investigated an X-ray binary source known as IGR J18214-1318. Results of the study, detailed in a paper published September 14 on the arXiv pre-print server, provide ...
An international team of astrophysicists has found distinctive signatures of black hole event horizons, unmistakably separating them from neutron stars, which are objects comparable to black holes in mass and size but confined ...

An international team of astronomers has conducted spectroscopic and photometric observations of a cataclysmic variable (CV) known as V1460 Her. Results of the study indicate that the system consists of a fast-spinning white ...
Imagine that the size of a bacterium is measured from a distance of about 4500 light-years. This would be an incredible measurement, considering that a bacterium is so small that a microscope is required to see it, and what ...
