JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing...
Catalog of Planetary Nebulae Detected by GALEX and Corollary Optical Surveys
Planetary nebulae (PNs) consist of an ionized envelope surrounding a hot central star (CSPN) that emits mostly at ultraviolet (UV) wavelengths. UV observations...

Una investigación internacional, liderada por científicos de la Universidad de Sheffield y con participación del Instituto de Astrofísica de Canarias, ha...
Descubren una enana blanca nacida de la fusión de dos estrellas
Un equipo internacional de investigadores liderado por la Universidad de Warwick y en colaboración con una científica del IAC ha descubierto una enana blanca de...
Discovery of Two Pulsating Extremely Low-mass Pre-white Dwarf Candidates in the TESS Eclipsing Binaries
We report the discovery of two new pulsating extremely low-mass pre-white dwarf (pre-ELMV) candidates in the Transiting Exoplanet Survey Satellite (TESS)...
El IAC hace seguimiento de la NOVA que aparece y desaparece cada 80 años
T. Corona Borealis podría ser el nombre de un personaje de ficción luchando por el trono de un reino violento, pero es mucho más interesante que eso, es cómo se...
Expanding the Ultracompacts: Gravitational-wave-driven Mass Transfer in the Shortest-period Binaries with Accretion Disks
We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This...
Finding White Dwarfs' Hidden Companions Using an Unsupervised Machine Learning Technique
White dwarfs (WD) with main-sequence (MS) companions are crucial probes of stellar evolution. However, due to the significant difference in their luminosities...
Draco C1 is a known symbiotic binary star system composed of a carbon red giant and a hot, compact companion—likely a white dwarf—belonging to the Draco dwarf...
