Stellar pulsations distribute key ingredient for life

As Carl Sagan famously said, "We're made of star stuff"—but how do stars distribute their essential "stuff" for life into space? NASA's telescope on an airplane, SOFIA, is finding some answers by watching pulsating stars ...

Beta Cephei-type pulsations detected in V453 Cygni

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected Beta Cephei-type pulsations in an eclipsing binary system known as V453 Cygni. The finding, detailed in a paper published May 15 on arXiv.org, ...

New type of pulsating star discovered

A star that pulsates on just one side has been discovered in the Milky Way about 1500 light years from Earth. It is the first of its kind to be found and scientists expect to find many more similar systems as technology to ...

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 ...

TESS first light on stellar physics

Using asteroseismic techniques, an international team searched for pulsations in a subsample of five thousand stars, from the 32 thousand observed in short cadence in the first two sectors (roughly the first two months of ...
