An international team in which researchers from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) are participating, observes how the magnetic waves which propagate through the solar atmosphere heat its outer layers. The results of this research are published today in the magazine Nature Physics.

Astronomers use the Gran Telescopio Canarias (GTC) to estimate the distance of the galaxy proposed as the source that emitted the extremely energetic neutrino detected last September with the “Ice Cube” experiment in Antarctica.

The Insituto de Astrofísica de Canarias(IAC) is participating in “Per aspera ad astra simul”, an initiave offering support for researcher mobility between the IAC and astronomical institutes in the Czech Republic and Slovakia.

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometric surveillance started in 2015 October, and a sequence of dipping began in 2017 May continuing on through the end of 2017, when the star was no longer visible from Earth. We distinguish four main 1%–2.5% dips, named “Elsie,” “Celeste,” “Skara Brae,” and “Angkor,” which persist on timescales from several days to weeks. Our main results so far are as follows: (i) there are no apparent changes of the stellar spectrum

Ayer se presentó en La Laguna el proyecto educativo que durante los próximos dos cursos llevará esta muestra por todos los centros de Canarias que quieran acercar la Astronomía al alumnado a través de imágenes celestes, formando previamente a docentes interesados.

Galaxy formation entails the hierarchical assembly of mass, along with the condensation of baryons and the ensuing, self-regulating star formation. The stars form a collisionless system whose orbit distribution retains dynamical memory that can constrain a galaxy's formation history. The ordered-rotation dominated orbits with near maximum circularity λz≃1 and the random-motion dominated orbits with low circularity λz≃0 are called kinematically cold and kinematically hot, respectively. The fraction of stars on `cold' orbits, compared to the fraction of stars on `hot' orbits, speaks directly
