By investigating dwarf novae identified by the Zwicky Transient Facility (ZTF), astronomers have discovered four binary systems. The objects turned out to be eclipsing accreting ultracompact white dwarf binaries. The finding ...
Using the AstroSat spacecraft, astronomers from the Birla Institute of Technology and Science in Pilani, India, have investigated a nearby open cluster NGC 6940. Results of the observational campaign, published December 21 ...
An international team of astronomers has observed a distant white dwarf known as WDJ 022558.21−692025.38. It turns out that the observed object is an eclipsing double white dwarf binary system. The finding is reported in ...
By analyzing the long-term, high-cadence continuous photometry from NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have investigated UU Columbae and Swift J0939.7-3224—two intermediate polars. Results ...
Astronomers have conducted photometric observations of a white dwarf known as J004917.14−252556.81. Results of the observational campaign detected photometric variability of this object, making J004917.14−252556.81 the ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a peculiar cataclysmic variable star. The newly found system, designated SDSS J134441.83+204408.3 (or J1344 for short) is a highly asynchronous, ...
Using data from various space telescopes, astronomers have investigated a variable X-ray source known as SWIFT J0503.7-2819. Results of the study suggest that this source is an intermediate polar. The finding was detailed ...
Using the AstroSat spacecraft, Indian astronomers have investigated an open cluster known as NGC 2506. The study identified more than 2,000 member stars of this cluster and provided more insights into its properties. The ...
Using ESA's XMM-Newton satellite and NASA's Chandra spacecraft, an international team of astronomers has investigated a peculiar behavior of quasi-periodic eruptions (QPEs) in an active galaxy known as GSN 069. Results of ...
Using ESA's XMM-Newton satellite, astronomers from the Columbia University in New York have inspected a peculiar cataclysmic variable system known as Swift J0503.7−2819. Results of the study, presented June 29 on arXiv.org, ...
