Optical Spectroscopic Observations of CI Camelopardalis
We present the results of optical spectroscopic observations of CI Cam. Double-peaked profiles were simultaneously observed for the first time in the hydrogen Balmer, He I λ6678 and Fe II lines during an observational run in 2001 September. An intermediate viewing angle of the circumstellar disk around the B[e] star is consistent with our data. A significant decrease in the intensity of the Hα ...

متن کاملLunar eclipse observations reveal anomalous thermal performance of Apollo reflectors
Laser ranging measurements during the total lunar eclipse on 2010 December 21 verify previously suspected thermal lensing in the retroreflectors left on the lunar surface by the Apollo astronauts. Signal levels during the eclipse far exceeded those historically seen at full moon, and varied over an order of magnitude as the eclipse progressed. These variations can be understood via a straightfo...
متن کاملInterferometric Studies of the extreme binary, Aurigae: Pre-eclipse Observations
We report new and archival K-band interferometric uniform disk diameters obtained with the Palomar Testbed Interferometer for the eclipsing binary star Aurigae, in advance of the start of its eclipse in 2009. The observations were intended to test whether low amplitude variations in the system are connected with the F supergiant star (primary), or with the intersystem material connecting the st...
متن کاملOBSERVATIONS OF THE 1991 ECLIPSE AT 3.5 mm WAVELENGTH
We report preliminary results of the partial eclipse seen from the BIMA millimeterwavelength interferometer in northern California. The use of an interferometer has many advantages over previous single-dish eclipse observations at 3 mm, and in particular it allows a quite different type of measurement of the height of the "3-mm limb" which is direct and precise : we find it to be 11.9" ± 0.4" a...
