Astronomers observe carbon-atmosphere white dwarf stars with the Hubble Space Telescope

Source: CRAQ

A team of researchers composed of astrophysicists from Québec, and led by Patrick Dufour, postdoctoral research at the Université de Montréal (UdeM) and member of the CRAQ, analyzed data recently obtained from the Hubble Space Telescope with its new instrument, the Cosmic Origin Spectrograph (COS). The work of the researchers (from the UdeM, the University of Colorado, and the Space Telescope Institute in Baltimore), confirmed the luminosity variations of three stars already observed with ground telescopes. They also discovered a new member of the pulsating white dwarf subgroup, for the first time with observations from space. (read more)
