First planet confirmed from the Calar Alto Observatory




An exoplanet is confirmed for the first time using an instrument built by the Calar Alto Observatory. It is the first planet orbiting a giant star whose confirmation is beyond any doubt.

The planetary nature of an object orbiting the giant star KIC 8219268 has been confirmed by using the radial velocity technique and the Calar Alto Fiber-fed Echelle spectrograph (CAFE), the first instrument built by the Spanish-German Astronomical Center, in Almería, Spain. Researchers from the Center of Astrobiology (CAB, INTA-CSIC), the Max-Planck Institut für Astronomy (MPIA, MPG), Centro de Astrofisica e Departamento de Física e Astronomia (Universidade do Porto), Instituto de Astronomía (UNAM) and from Calar Alto (CAHA), in Spain, Germany, Portugal and Mexico have applied this well understood methodology and have obtained a mass similar to Jupiter. The planet, named Kepler-91b, is located extremely close to the star. This is the first planet ever confirmed based on data acquired from Calar Alto Observatory.

Saturn’s hexagon from Calar Alto and from space

teaser lowResearchers from the Planetary Sciences Group of the Basque Country University (UPV/EHU) unveil some secrets of Saturn’s mysterious hexagonal wave, among them its rotational period, that may be the rotation period of the planet itself. The study, published in the scientific journal Geophysical Research Letters, has been based on data taken at Calar Alto Observatory and by the space probe Cassini

Calar Alto Observatory on strike

CA-logo STRIKE lowCalar Alto Observatory is on strike from March the 27th to April the 2nd, 2014. The call for strike was made by Calar Alto workers, to show their disagreement with the severe cut offs in the Observatory's budget decided by the Spanish Higher Council for Scientific Research (CSIC) and the German Max Planck Society (MPG).
