Phys.org / HD 21997 is a high-frequency Delta Scuti pulsator, observations find
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. ...
Phys.org / New young and warm Jupiter-like exoplanet detected
An international team of astronomers reports the detection of a new young and warm exoplanet orbiting a distant star. The newfound alien world, designated TOI-4862 b (or NGTS-30 b), is similar in size and mass to Jupiter. ...
Phys.org / Astronomers discover the longest-period classical Cepheid in our galaxy
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 ...
Phys.org / Observations reveal complex morphology of Big Three Dragons
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has observed a merging galaxy system known as B14-65666, dubbed "Big Three Dragons." ...
Phys.org / Luminous quasar PDS 456 explored with MUSE
Using the Multi Unit Spectroscopic Explorer (MUSE) at the Very Large Telescope (VLT) in Chile, an international team of astronomers has inspected a luminous quasar known as PDS 456. Results of the observational campaign, ...
Phys.org / Astronomers find 10 new millisecond pulsars in globular cluster Terzan 5
Using the MeerKAT radio telescope, an international team of astronomers has detected 10 new millisecond pulsars in a Galactic globular cluster known as Terzan 5. The finding, which makes Terzan 5 the most pulsar-rich globular ...
Phys.org / JWST observations explore molecular outflows of a nearby merging galaxy
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby merging galaxy known as NGC 3256. Results of the observational campaign, presented March 21 on the pre-print server arXiv, ...
Phys.org / New cataclysmic variable discovered by astronomers
By analyzing the data from ESA's XMM-Newton and Gaia satellites, astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany and elsewhere have detected a new magnetic cataclysmic variable system, most ...
Phys.org / Three new millisecond pulsars detected with MeerKAT
Using the MeerKAT radio telescope in South Africa, an international team of astronomers has detected three new millisecond pulsars in the globular cluster Messier 62 (also known as NGC 6266). The finding was detailed in a ...
Phys.org / New nearby mini-Neptune exoplanet discovered
An international team of astronomers reports the discovery of a new mini-Neptune exoplanet orbiting a nearby star. The newfound alien world, designated TOI-4438 b is about 2.5 times larger than the Earth. The finding was ...
Phys.org / Hot post-asymptotic giant branch star discovered in globular cluster ESO 37-1
Astronomers have discovered a new post-asymptotic giant branch (PAGB) star in a Galactic globular cluster known as ESO 37-1 (or E3 for short) and derived its fundamental parameters. The finding is reported in a research paper ...
Phys.org / Four new DAQ white dwarfs discovered
Astronomers from the University of Oklahoma and their colleagues report the detection of four white dwarf stars of a recently discovered rare DAQ spectral subclass. The newfound white dwarfs are slightly more massive than ...
Phys.org / Astronomers explore stellar populations of an extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope, astronomers have conducted near- and mid-infrared observations of an extremely metal-poor blue compact dwarf galaxy known as I Zwicky 18. Results of the observational campaign, presented ...
Phys.org / Astronomers discover a rare eclipsing X-ray binary
An international team of astronomers reports the detection of a rare eclipsing Be/X-ray binary system as part of the Swift Small Magellanic Cloud (SMC) Survey (S-CUBED). The finding was detailed in a research paper published ...
Phys.org / JWST observations shed more light on the nature of a distant galaxy cluster
Astronomers from the Nanjing University in China and elsewhere have performed high-resolution observations of a distant galaxy cluster known as CL J1001+0220 using the James Webb Space Telescope (JWST). The observational ...
