Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have observed a young star designated HD 21997. Results of the new observations indicate that the studied object is a high-frequency Delta Scuti pulsator. ...
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 various ground-based facilities and space telescopes, astronomers have observed an accretion outburst that recently occurred on a young variable star known as V1741 Sgr. Results of the observations, published January ...
Using NASA's Spitzer and WISE space telescopes, astronomers from the Steward Observatory and elsewhere have observed a well-known variable star designated RZ Piscium. They found that the star's circumstellar debris disk is ...
An international team of astronomers has investigated EX Lupi—a young T-Tauri star in the constellation of Lupus and an archetype of EXor stars. The study, presented in a paper published August 23 on the pre-print server ...
By analyzing the data from various ground-based facilities and space telescopes, European astronomers have investigated the nature of a peculiar object known as PM 1-322. As a result, they found evidence indicating that PM ...
Using the Nanshan One-meter Wide-field Telescope (NOWT), astronomers from China have performed a photometric survey of the old open cluster NGC 188. In result, they identified many variable stars, one of which was detected ...
Using data from NASA's Kepler spacecraft, astronomers from the Pedagogical University of Cracow, Poland, and elsewhere have detected 278 variable stars in the open cluster NGC 6791 and its surroundings. The finding was reported ...
Using three ground-based telescopes in Chile, astronomers have conducted a search for variable stars in the open cluster NGC 6611. In result, they detected 95 variables and the majority of them are most likely cluster members. ...
