MODE (service or user) service
TIME 0.25 hours X 90 nights = 22.5 hours X 1.5 service = 3.6 nights
TRAINING RUN N/A
OBSERVER/TRAINER N/A
INTERPOLATED PROGRAMS OK? yes
PREFERRED DATES any
ACCEPTABLE DATES any
ACCEPTABLE MOON any
CADENCE 1 set of observations (5 fields) every other night
PREFERRED SETUP CCD+IR
EXPOSURE TIMES (1 minute exposure + 2 minutes overhead) x 5 target fields
= 15 minutes per observation.
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.

PREFERRED DATES AUG - JAN
ACCEPTABLE DATES AUG - JAN
ACCEPTABLE MOON dark/gray time preferred for the fainter targets
CADENCE only one visit per object (including two gratings)
PREFERRED SETUP 26/Ia AND 47/Ib
EXPOSURE TIMES single observations of 3600 sec each with each grating,
two gratings per target
SCIENTIFIC DESCRIPTION Spectroscopic Monitoring of 'Naked' Seyfert 2 (NS2):
NS2s are found to show x-ray absorption but have no broad
lines and therefore no broad line regions. We believe
this is due to their changing from type 1/1.8 to type 2
which we will test with these new observations.
