The Subaru Seminar is usually held in Room 104 of the Hilo Base Facility, adjacent to the main lobby. Everyone is welcome to attend. If you are interested in giving a seminar, please contact Subaru seminar organizers (Tae-Soo Pyo, Sherry Yeh, Nagayoshi Ohashi) by email : sseminar_at_subaru.naoj.org (please change"_at" to @).

" GATS and Pulsating Stars "

Magdalena Polińska

(Adam Mickiewicz University)


I will describe a project which is managed by Astronomical Observatory Institute of Adam Mickiewicz University in Poznań, Poland - Global Astrophysical Telescope System. The GATS is primarily intended for stellar high resolution spectroscopy with a global network of robotic telescopes and consists of two telescopes (one in Poland and second in US). The talk will also present project focused on atmospheres of β Cephei and SPB stars in the young open clusters and Galactic field. The pulsation mechanism of proposed variables strongly depends on the abundances of iron-peak elements. From the analysis of high-resolution, high signal-to-noise spectra we will obtain stellar atmosphere parameters and chemical abundances. This will allow to determine the relationships between chemical abundances and pulsational parameters of β Cephei and SPB stars.


Seminars are also held at JAC, CFHT, and IfA.
