Asymmetric Light Curves of Black Hole Binaries and the Doppler Beaming Effect [PDF]
Journal of Astronomy and Space Sciences, 2002 Black hole binary candidates are known to be composed of a black hole with 10Msolar and a K or M type companion. Because the companion is believed to fill the Roche lobe that is very aspherical, the light curves of black hole binaries are characterized ...

A Photometric Study of Near-Contact Binary ZZ Aur [PDF]
Journal of Astronomy and Space Sciences, 2002 The BVR CCD full light curves of ZZ Aur were obtained as one of the near-contact binary observing programs at the Sobaek Mt. Observatory during Feb. 2000 - Feb. 2001. From the present observations, three primary and seven secondary times of minimum light

Classical Machine Learning Techniques in the Search of Extrasolar Planets
CLEI Electronic Journal, 2019 The field of astronomical data analysis has experienced an important paradigm shift in the recent years. The automation of certain analysis procedures is no longer a desirable feature for reducing the human effort, but a must have asset for coping with ...

The Light Curve of S Andromedae [PDF]
, 2002 Historical observations of S And, in combination with the color versus rate-of-decline relationship for well-observed SN 1991bg-like supernovae, are used to estimate a rate of decline Delta m15 (B) = 2.21 and an intrinsic color at maximum [B(0) - V(0)]o =

Swift/BAT and RXTE Observations of the Peculiar X-ray Binary 4U 2206+54 - Disappearance of the 9.6 Day Modulation [PDF]
, 2006 Observations of the high-mass X-ray binary 4U 2206+54 with the Swift Burst Alert Telescope (BAT) do not show modulation at the previously reported period of 9.6 days found from observations made with the Rossi X-ray Timing Explorer (RXTE) All-Sky Monitor

The bright optical/NIR afterglow of the faint GRB 080710 - Evidence for a jet viewed off axis [PDF]
, 2009 We investigate the optical/near-infrared light curve of the afterglow of GRB 080710 in the context of rising afterglows. Optical and near-infrared photometry was performed using the seven channel imager GROND and the Tautenburg Schmidt telescope.

An Algorithmic Approach for Detecting Bolides with the Geostationary Lightning Mapper
Sensors, 2019 The Geostationary Lightning Mapper (GLM) instrument onboard the GOES 16 and 17 satellites can be used to detect bolides in the atmosphere. This capacity is unique because GLM provides semi-global, continuous coverage and releases its measurements ...

Determining the Rotation Periods of an Inactive LEO Satellite and the First Korean Space Debris on GEO, KOREASAT 1 [PDF]
Journal of Astronomy and Space Sciences, 2016 Inactive space objects are usually rotating and tumbling as a result of internal or external forces. KOREASAT 1 has been inactive since 2005, and its drift trajectory has been monitored with the optical wide-field patrol network (OWL-Net).
