Astronomers from the University of Warsaw, Poland and elsewhere have detected a new classical Cepheid variable star. The newfound star, which received designation OGLE-GD-CEP-1884, has the longest pulsation period known among ...
An international team of astronomers has performed spectroscopic observations of a variable star known as V708 Car. Results of the observational campaign, reported in a paper published February 20 on the pre-print server ...
Using the Gemini Observatory, astronomers have detected 15 new periodic and non-periodic variables in a nearby galaxy known as NGC 247. The finding, reported in a paper published July 29 on the arXiv pre-print repository, ...
Italian astronomers have reported the discovery of a new lithium-rich galactic Cepheid star, identified by high-resolution spectroscopic observations. The newfound object, designated V363 Cas, is the fifth lithium-rich classical ...
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 ...
Astronomers have performed a comprehensive study of stellar populations in the young globular cluster NGC 1866. The new study confirms that the cluster hosts multiple stellar populations, which could have implications for ...
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 ...
A team of researchers at the University of Warsaw has created the most accurate 3-D model of the Milky Way Galaxy to date. In their paper published in the journal Science, the group explains how they used measurements from ...
Astronomers using NASA's Hubble Space Telescope say they have crossed an important threshold in revealing a discrepancy between the two key techniques for measuring the universe's expansion rate. The recent study strengthens ...
