Tellurium is detected in one of its places of origin

28/06/2018
A tellurium emission line and a bromine emission line have been located for the first time in the infrared spectra of two planetary nebulae. These are the clearest detections of ions belonging to these two heavy elements in one of the places where they form. The study has been led by Simone Madonna, a PhD student at the IAC, with the participation of his supervisor, Jorge García Rojas, IAC Severo Ochoa advance postdoctoral researcher. The data has been obtained with the EMIR spectrograph, on the Gran Telescopio Canarias at the Roque de los Muchachos Observatory (La Palma), and IGRINS, on the Harlan J. Smith Telescope, at the McDonald Observatory (Texas). >> Read more
