First discovery of a magnetic field in a normal delta Scuti star
Brussels, Belgium (SPX) Oct 21, 2015
Coralie Neiner, from the Observatoire de Paris (LESIA/CNRS/UPMC/Universite Paris Diderot) and Patricia Lampens, from the Royal Observatory of Belgium discovered the first magnetic delta Scuti star through spectropolarimetric observations at the CFHT telescope in Hawaii. The delta Scuti stars are pulsating stars some of which show signatures attributed to a second type of pulsations. The discovery shows that it is actually the signature of a magnetic field. This has important implications for under ... read more
