An international team composed of Drs. Sylvain G. Korzennik, from the Center for Astrophysics | Harvard & Smithsonian , and Antonio Eff-Darwich Peña, from the University of La Laguna and the Instituto de Astrofísica de Canarias, has published a pioneering study aimed at improving our understanding of the Sun’s internal structure. The work, published in The Astrophysical Journal , stands out for its use of exceptionally long helioseismic time series, exceeding twenty-five years of continuous observations, to analyze the deepest layers of the Sun. Helioseismology is the study of patterns of

An international scientific team, including members of the Instituto de Astrofísica de Canarias (IAC), has launched an ambitious program to map exoplanets located around the Neptunian Desert —a region around stars where planets the size of Neptune are very rare— in order to better understand the mechanisms of planetary system evolution and formation. This scientific expedition has delivered its first results with the observation of the TOI-421 planetary system. Analysis of this system reveals a surprisingly inclined orbital architecture, offering new insights into the chaotic history of

A greedy white dwarf star in our own Milky Way galaxy is devouring its closest celestial companion at a rate never seen before, according to an international study involving the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL). The research, published in the journal Monthly Notices of the Royal Astronomical Society , found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Experts think the stars are locked in an "extraterrestrial tango" as they orbit each other every
