The actual dates of the campaign are 11
January-1 February (UT). Some additional time during the first weeks of
February may also be scheduled.
We are pleased to announce a new electronic newsletter devoted to asteroseismology of solar-type stars. This newsletter is founded to disseminate timely information on programs, meetings, and results related to asteroseismology, and to assist in the development of a world-wide network for the study of acoustic oscillations in solar-type stars. The first issue of SONGNews includes a report on our Special Session at the AAS meeting in Madison in June, recent abstracts related to asteroseismology, meeting announcements, and an invitation to participate in the Procyon Campaign in early 1997.
Initially, we hope to distribute SONGNews quarterly. If you are interested in subscribing, send e-mail to songnews@noao.edu. The first issue was distributed in early July, and is available via the NOAO homepage at http://www.noao.edu (click on SONG).
During the last three weeks of January 1997, the Stellar Oscillations
Network Group at NOAO will conduct a campaign to monitor the star
Procyon for p-mode oscillations. Observations will be obtained on the
Coudé Feed telescope on Kitt Peak near Tucson, Arizona, at a reciprocal
dispersion of 0.4 Å/pixel, covering the region from 3800-5200 Å. Primary
emphasis will be on the measurement of the equivalent widths of H,
H, and H for asteroseismology.
The actual dates of the campaign are 11
January-1 February (UT). Some additional time during the first weeks of
February may also be scheduled.
We are interested in developing collaborations with other observatories during this period, both to extend coverage to times when Procyon cannot be observed from Kitt Peak, and to monitor the star using other techniques such as Doppler velocity variation or photometric variation.
If you are interested in participating in this campaign, please contact one of us at NOAO or e-mail to song@noao.edu for details.
