Plaskett 1.8 m Observations of Starlink Satellites
The Astronomical Journal, 2022 Abstract We present observations of 23 Starlink satellites in the g′ bandpass, obtained from the Dominion Astrophysical Observatory’s Plaskett 1.8 m telescope. The targets include a mixture of satellites with and without brightness mitigation measures (i.e., visors).

The eclipsing, double-lined, Of supergiant binary Cyg OB2-B17 [PDF]
, 2010 Massive, eclipsing, double-lined, spectroscopic binaries are not common but are necessary to understand the evolution of massive stars as they are the only direct way to determine stellar masses.

On the anomaly of Balmer line profiles of A-type stars. Fundamental binary systems [PDF]
, 2002 In previous work, Gardiner et al. (1999) found evidence for a discrepancy between the Teff obtained from Balmer lines with that from photometry and fundamental values for A-type stars.

A new HW Vir binary from the Palomar Transient Factory: PTF1 J072455.75+125300.3 - An eclipsing subdwarf B binary with a M-star companion [PDF]
, 2015 We report the discovery of an eclipsing binary -- PTF1 J072456$+$125301-- composed of a subdwarf B (sdB) star ($g'=17.2^m$) with a faint companion. Subdwarf B stars are core helium-burning stars, which can be found on the extreme horizontal branch. About

Starlink corn: a risk analysis. [PDF]
Environmental Health Perspectives, 2002 Modern biotechnology has dramatically increased our ability to alter the agronomic traits of plants. Among the novel traits that biotechnology has made available, an important group includes Bacillus thuringiensis-derived insect resistance. This technology has been applied to potatoes, cotton, and corn. Benefits of Bt crops, and biotechnology generally,
