V473 Lyr has a low-mass companion, study suggests

Using ESA's XMM-Newton spacecraft, astronomers have conducted X-ray observations of a peculiar Cepheid variable star known as V473 Lyr. Results of the study suggest that this star has a young, low-mass companion. The finding ...

The interiors of stars

The interiors of stars are largely mysterious regions because they are so difficult to observe directly. Our lack of understanding about the physical processes there, like rotation and the mixing of hot gas, introduces considerable ...

Waiting for Betelgeuse: what's up with the tempestuous star?

Have you noticed that Orion the Hunter—one of the most iconic and familiar of the wintertime constellations—is looking a little… different as of late? The culprit is its upper shoulder star Alpha Orionis, aka Betelgeuse, ...

Data milestone achieved in variable star repository

Compiling together multiple pieces of information for each of a million-plus objects is no easy or quick task, but that is exactly what Sebastián Otero, Patrick Wils, Patrick Schmeer, and Klaus Bernhard did. Due to this ...

Three new Beta Cephei stars detected

Using NASA's prolonged Kepler mission, known as K2, astronomers have identified three new Beta Cephei stars. The newly found trio is an important addition to the still short list of known stars of this type. The finding is ...

Astronomers identify dozens of new Beta Cephei stars

Using the Kilodegree Extremely Little Telescope (KELT), astronomers have detected 86 new Beta Cephei (β Cep) stars in the Milky Way galaxy. The discovery, detailed in a paper published July 26 on the arXiv pre-print repository, ...

Astronomers detect 130 short period variable stars

By conducting photometric observations of the open cluster Stock 8 and its surrounding region, astronomers have identified 130 short-period variable stars, classifying 51 of them as members of the cluster. A paper detailing ...
