Optical and Infrared Photometry of the nearby SN 2017cbv [PDF]
The Astrophysical Journal, 2018 Abstract On 2017 March 11, the DLT40 Transient Discovery Survey discovered SN 2017cbv in NGC 5643, a Type 2 Seyfert Galaxy in the Lupus Constellation. SN 2017cbv went on to become a bright Type Ia supernova, with a V max of 11.51 ± 0.05 mag.

The Anisoplanatic Point Spread Function in Adaptive Optics [PDF]
, 2006 The effects of anisoplanatism on the adaptive optics point spread function are investigated. A model is derived that combines observations of the guide star with an analytic formulation of anisoplanatism to generate predictions for the adaptive optics ...

bRing: An observatory dedicated to monitoring the $\beta$ Pictoris b Hill sphere transit [PDF]
, 2017 Aims. We describe the design and first light observations from the $\beta$ Pictoris b Ring ("bRing") project. The primary goal is to detect photometric variability from the young star $\beta$ Pictoris due to circumplanetary material surrounding the ...

Optical Photometry of Black-Hole Candidates [PDF]
Symposium - International Astronomical Union, 1996 The orbital light curves of SXTs are discussed. In principle, the orbital inclination can be determined from the ellipsoidal variations, allowing a complete solution for the component masses. Complications in this analysis are described, and the evidence for superhumps in the light curves is reviewed.

Optical and Radio Surface Photometry of NGC 891 [PDF]
Symposium - International Astronomical Union, 1990 A general correlation between the radio and optical continuum surface brightness has been found in the edge-on galaxy NGC 891. This suggests that the relativistic electrons are produced/accelerated in the vicinity of evolved stars or stellar remnants which have a spatial distribution similar to old disk stars.

TASS Mark IV Photometric Survey of the Northern Sky [PDF]
, 2006 The Amateur Sky Survey (TASS) is a loose confederation of amateur and professional astronomers. We describe the design and construction of our Mark IV systems, a set of wide-field telescopes with CCD cameras which take simultaneous images in the $V$ and $
