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.

TESS mission (MIT-NASA), with will examine more than two hundred thousand stars along its two years life, constitutes one of the presently most important project for the search of exoplanets, as it will detects planets that can be studied and characterized with instruments that exist today on earth. One of such instruments that will analyze TESS data is CARMENES, operating at the Calar Alto Observatory (Almería) 3.5m telescope, and whose team has already began receiving TESS planets detections alerts.

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

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 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.

Best 2017 PhD in Astronomy uses CALIFA data

June 28th 2018

Laura Sánchez-Menguiano was awarded the best 2017 PhD thesis in Astronomy by the Spanish Astronomical Society. Laura’s thesis uses CALIFA data, taken with the PMAS Integral Field Spectrograph at the 3.5-m Calar Alto telescope, to scrutinize the spiral structure in disk galaxies.

Most galaxies in the local Universe display beautiful spiral arms, concentrations of bright stars in a rotating disk, like a whirl around a bulge made of older stars. Although omnipresent, the formation and persistence of this twisting spiral structure is still not well understood, despite the arms should play a major role in the chemical and dynamical evolution of disk galaxies.
