The Time Domain Spectroscopic Survey (TDSS) 4-6 Year Optical Spectroscopic Survey already begun 260,000 spectra of variables selected from PanSTARRs science pathfinder for LSST and other TD imaging surveys piggybacks on SDSS IV eBOSS survey covers ~7500 deg2 of sky to i~21.5mag 90% will be discovery spectra Science on brown dwarfs, eclipsing binaries, CVs, RRLyr, Quasars Students welcome! ... Spectra probe a wide range of astrophysics. ...

This section describes the calculation by which Aristarchus used the duration of a total lunar eclipse to deduce the distance of the Moon. ... This lesson plan supplements: "How Distant is the Moon--1", section #8c: on disk Shipprc2.htm , on the web . ... The shadow of the Earth at the Moon's distance is narrower than the Earth, because the Sun is seen not as a point but as a disk 0.5 degrees wide. ... An eclipse of the Moon is the passage of the Moon through the shadow of the Earth. ...

... Proximity e#ects of com­ ponents (reflection of radiation and surface gravity darkening) are taken into account. ... As an example, we consider the Algol (# Persei) system, where an eclipsing pair (Algol A­B) is accompanied by the third component (Algol C). ... The surface temperature distribution for Algol A­B system before (upper plot) and after (lower plot) correction for temperature due to the irradiation e#ect. ... We solve this equation by the iterative Newton­Raphson method. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...
