Description:
Seismology of stars provides insight into the physical mechanisms taking place in their interior, with modes of oscillation probing different layers. Low-amplitude acoustic oscillations excited by turbulent convection were detected four decades ago in the Sun and more recently in low-mass main-sequence stars. Using data gathered by the Convection Rotation and Planetary Transits mission, we report here on the detection of solar-like oscillations in a massive star, V1449 Aql, which is a known large-amplitude (beta Cephei) pulsator.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Belkacem, Kevin -- Samadi, Reza -- Goupil, Marie-Jo -- Lefevre, Laure -- Baudin, Frederic -- Deheuvels, Sebastien -- Dupret, Marc-Antoine -- Appourchaux, Thierry -- Scuflaire, Richard -- Auvergne, Michel -- Catala, Claude -- Michel, Eric -- Miglio, Andrea -- Montalban, Josefina -- Thoul, Anne -- Talon, Suzanne -- Baglin, Annie -- Noels, Arlette -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1540-2. doi: 10.1126/science.1171913.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Etudes Spatiales et d'Instrumentation en Astrophysique, CNRS (UMR 8109), Observatoire de Paris, Place J.
