A cold wind during the discovery outburst of a black hole

Normalized spectra of the GTC-1 (blue) and GTC-2 epochs (black), both centred at Hα. Telluric bands and diffuse interstellar bands, as well as reference velocities (1000 km/s and 1250 km/s) have been marked to highlight the blue-shifted absorption produced by the wind.

    CARMENES exoplanet hunter scientific meeting

    The 19th scientific meeting of CARMENES, a collaboration of more than 100 scientists from 11 Spanish and German institutions aimed at studying extrasolar planets around M-type dwarf stars, the lowest mass stars, was held this week at the IACTEC facilities in La Laguna (Tenerife, Spain). Since it became operational in 2016, CARMENES has analysed more than 360 such stars, leading to the discovery of more than 65 new planets, making it the most efficient instrument and mapper in the study of planets around very low-mass stars, with 30 % of the total number of planets discovered in this range
