SCIENTIFIC DESCRIPTION We have discovered several dozen, new, massive eclipsing binaries in the Small and Large Magellanic Clouds. We are now engaged in follow up spectroscopy with the Magellan telescopes to obtain masses. However, time limitations will mean that we can only obtain several spectra of each target, so must rely on light curves to determine the orbital period and to plan the spectroscopy at times of quadrature when velocity measurements of both components are possible. The new observations of stars in one SMC and four LMC clusters will also help us create well populated light curves for modeling (to obtain orbital inclination) and look for effects of apsidal motion (a potential test of the interior structure of massive stars. ------------------------------------------------------------------------------------------ GSU PRIORITY 4 ------------------------------------------------------------------------------------------ TELESCOPE + INSTRUMENT 1.5m + RCSpec TITLE Spectral Monitoring of Luminous Blue Variables (LBVs) ID # GSTU74 PI Noel Richardson (GSU), Doug Gies (GSU) CONTACT richardson@chara.gsu.edu/404-413-6021, gies@chara.gsu.edu MODE (service or user) service TIME 18 hours X 1.2 tax X 1.5 service = 32.4 hours = 3.4 nights TRAINING RUN N/A OBSERVER/TRAINER N/A INTERPOLATED PROGRAMS OK? yes PREFERRED DATES any ACCEPTABLE DATES any ACCEPTABLE MOON any CADENCE 4-6 total spectra needed/target when available PREFERRED SETUP 47/Ib or 47/Id EXPOSURE TIMES varies by target (10-40 minutes, including overhead) SCIENTIFIC DESCRIPTION Fourth semester of 3-year project to monitor LBVs to search for evidence of spectroscopic variations caused by multiplicity and envelope pulsation.
