A Study of Pi Aquarii During a Quasi-normal Star Phase: Refined Fundamental Parameters and Evidence for Binarity (2002)

Bjorkman, Karen S., Miroshnichenko, Anatoly S., McDavid, David, Pogrosheva, Tatiana M.

We present the results of recent multicolor photometric and high-resolution spectroscopic observations of the bright Be star Pi Aquarii. Observational data collected from the literature were used to...

A Study of π Aquarii during a Quasi-Normal Star Phase: Refined Fundamental Parameters and Evidence for Binarity (2002)

Karen S. Bjorkman, Anatoly S. Miroshnichenko, David Mcdavid, Tatiana M. Pogrosheva

We present the results of recent multicolor photometric and high-resolution spectroscopic observations of the bright Be star # Aqr. Observational data collected from the literature were used to study...

A Useful Approximation for Computing the Continuum Polarization of Be Stars (2001)

McDavid, David

This paper describes a practical model for the polarization of Be stars which can be used to estimate roughly the physical parameters for optically thin circumstellar envelopes from broadband UBVRI...

A Search for Intrinsic Polarization in O Stars with Variable Winds (1999)

McDavid, David

New observations of 9 of the brightest northern O stars have been made with the Breger polarimeter on the 0.9~m telescope at McDonald Observatory and the AnyPol polarimeter on the 0.4~m telescope at...

Multicolor Polarimetry of Selected Be Stars: 1995-98 (1998)

McDavid, David

A new polarimeter called AnyPol has been used at Limber Observatory for four years to annually monitor the broadband linear polarization of a sample of bright northern Be stars. This is the fourth...
