Stellar Variability and Flare Rates from Dome A, Antarctica using 2009 and 2010 CSTAR Observations
Ryan J. Oelkers, Lucas M. Macri, Lifan Wang +12
The Chinese Small Telescope ARray (CSTAR) carried out high-cadence time-series observations of 20.1 square degrees centered on the South Celestial Pole during the 2008, 2009 & 2010…
Difference Image Analysis of Defocused Observations with CSTAR
Ryan J. Oelkers, Lucas M. Macri, Lifan Wang +13
The Chinese Small Telescope ARray (CSTAR) carried out high-cadence time-series observations of 27 square degrees centered on the South Celestial Pole during the Antarctic winter se…
Photometry of Variable Stars from Dome A, Antarctica: Results from the 2010 Observing Season
Lingzhi Wang, Lucas M. Macri, Lifan Wang +17
We present results from a season of observations with the Chinese Small Telescope ARray (CSTAR), obtained over 183 days of the 2010 Antarctic winter. We carried out high-cadence ti…
Geometry and velocity structure of HD 44179's bipolar jet
Joshua D. Thomas, Adolf N. Witt, Jason P. Aufdenberg +4
In this paper we analyse a set of 33 optical spectra, which were acquired with the ARCES echelle spectrograph (R = 38,000) on the 3.5-m telescope at the Apache Point Observatory. W…
Photometry of Variable Stars from Dome A, Antarctica
Lingzhi Wang, Lucas M. Macri, Kevin Krisciunas +18
Dome A on the Antarctic plateau is likely one of the best observing sites on Earth thanks to the excellent atmospheric conditions present at the site during the long polar winter n…
The nature of the Na I D-lines in the Red Rectangle
Joshua D. Thomas, Adolf N. Witt, Jason P. Aufdenberg +6
In this paper we examine the profiles of the complex Na I D-lines in the Red Rectangle. The spectra were acquired with the ARCES échelle spectrograph R = 38,000 on the 3.5-m telesc…
Characterisation of Sloan Digital Sky Survey Stellar Photometry
Masataka Fukugita, Naoki Yasuda, Mamoru Doi +2
We study the photometric properties of stars in the data archive of the Sloan Digital Sky Survey (SDSS), the prime aim being to understand the photometric calibration over the enti…
