It is expected that the TESS mission, developed at the Massachusetts Institute of Technology (MIT) and NASA, finds about one thousand five hundred planets around other stars in its two years of operation. CARMENES spectrograph team, located at the Calar Alto Observatory, has begun to receive the alerts in order to confirm and analyze TESS detections

The strange case of HuBi1, an inside-out stellar corpse

Planetary nebulae are the descendants of low- to intermediate-mass stars, like our Sun. They form at late evolutionary stages, when their progenitor stars expel their envelopes, which are then photoionized by the hot white dwarf at the nebular center. The regions closer to the central star have species with higher ionization than the farther, cooler regions.

An extraordinarily dense region tests the theory of structure formation in the universe

According to the most accepted cosmological theory, before the galaxies formed there were already dark matter concentrations that acted as a binder: the gas that would give rise to the first galaxies was concentrated in these lumps of dark matter (a type of matter that does not emit light and only interacts gravitationally), and this type of matter continues to be the majority in galaxies and clusters of galaxies, in the form of enormous haloes around luminous matter.

The planetary nebula HuBi 1, a rebel with a cause

Planetary nebulae, the descendants of low- and intermediate-mass stars, have characteristic onion-like ionization structure, with the highest ionization species closer to the central star. This is true for all planetary nebulae, but HuBi 1, which shows an inverted ionization inner shell. There is a reason for this oddity, a peculiar stellar evolution of its central star, which makes HuBi 1 the missing link of the population of cool C-rich central stars of planetary nebulae.

Similar to Jupiter, Kelt-9 is hotter than some stars. Thanks to the CARMENES instrument at Calar Alto Observatory, astronomers detected an extensive hydrogen envelope around Kelt-9b that escapes and is being captured by the star

The atmosphere of Kelt-9b, the hottest known planet, is being dragged towards its star

The Kelt-9b conditions are infernal: it rotates extremely close to its host star, Kelt-9, whose temperature doubles that of the Sun. It is the hottest exoplanet discovered, and a recent study with the CARMENES instrument at Calar Alto, has revealed the presence of an hydrogen atmosphere around Kelt-9, which is being dragged and captured by the gravitational force of its star. Led by the Max Planck Institute for Astronomy, the result has been published in Nature Astronomy.

At 22:25 in the evening (local time) of December 11 a brilliant fireball crossed the south of Spain. The fireball, which overflew the provinces of Granada and Jaén, could be seen from much of the country. The phenomenon has been recorded from the Sierra Nevada Observatory (Granada), as well as from the meteor detection stations operating under the SMART Project from the observatories of La Hita (Toledo), Calar Alto (Almería), La Sagra (Granada) and Seville.

Sierra Nevada Calar Alto

The Sierra Nevada Observatory (OSN) is a high mountain observatory located in Loma de Dilar, in the ski resort of the Sierra Nevada mountain range (Granada). The OSN is operated, maintained and supplied by the Instituto de Astrofísica de Andalucía (IAA-CSIC). It consists of a main building which hosts two Nasmyth optical telescopes of 90-cm and 1.50-m diameter each, as well as a 60-cm IR semi-automated telescope and a 35-cm telescope.

The German-Spanish Astronomical Center at Calar Alto is located in the Sierra de Los Filabres (Andalucía, Southern Spain) north of Almeria. It is operated jointly by the Max-Planck-Institut für Astronomie (MPIA) in Heidelberg, Germany, and the Instituto de Astrofísica de Andalucía (CSIC) in Granada/Spain. Calar Alto provides three telescopes with apertures of 1.23m, 2.2m and 3.5m to the general community. A 1.5m-telescope, also located on the mountain, is operated under the control of the Observatory of Madrid.

Take a taxi to the IAA or your hotel directly. There are some buses from the aiport to Granada, but they are not syncronous with the planes...

At the train station, ask for Av. de la Constitución and get on bus LAC to Palacio de Congresos. Get off Palacio de Congresos stop and change to bus S2, direction to Villa Argaz. This bus has a stop very close to the IAA, only a few meters.

At the bus station, get on bus SN2 to Palacio de Congresos. Get off at the bus stop Tierno Galván - Palacio de Congresos and change to bus S2 to Villa Argaz. The S2 route passes in front of the IAA. Get off at the first stop of Camino Bajo de Huétor Street, then walk for a few seconds and you'll be here.
