A cold wind during the discovery outburst of a black hole
We present 12 epochs of optical spectroscopy taken across the discovery outburst of the black hole (BH) candidate MAXI J1803-298 with the Gran Telescopio...
A conference celebrates 60 years in astrophysics by IAC researcher John Beckman
On November 6th and 7th a meeting will be held in the Museum of Science and the Cosmos in La Laguna, to celebrate the dedication to astrophysics during 60 years...
A crucial test for astronomical spectrograph calibration with frequency combs
Laser frequency combs (LFCs) are well on their way to becoming the next-generation calibration sources for precision astronomical spectroscopy. This development...
A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star
Ultrashort-period (USP) exoplanets have orbital periods shorter than 1 day. Precise masses and radii of USP exoplanets could provide constraints on their...
A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and...
Leo I is one of the youngest dwarf spheroidal (dSph) galaxies in the Local Group. Its relative isolation, extended and complex star formation history (SFH), and...
A giant exoplanet orbiting a very-low-mass star challenges planet formation models
Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion...
A giant interstellar bubble being grown in the Andromeda Galaxy
An international team of astrophysicists that includes researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has...
A giant interstellar bubble being grown in the Andromeda galaxy
The combination of a white dwarf mass close to the Chandrasekhar limit (1.4 solar masses) and a fast hydrogen accretion rate (10 -7 solar masses per year) from...
