Stellar Photometry with the Optical Monitors [PDF]

open access: yesInternational Astronomical Union Colloquium, 1993
AbstractThe Optical Monitors are small optical telescopes which will fly on board of the X-ray satellites SPECTRUM-X-GAMMA (JET-X experiment) and XMM. Their main scientific applications are the simultaneous observations (imaging) in the optical and UV band of the optical counterparts of X-ray sources, with limiting magnitudes of about mv=22 (JET-X) and

The photometry of optical instruments [PDF]

open access: yesTransactions of the Optical Society, 1922
The use of a portable surface-brightness photometer of the polarisation type for the measurement of the fraction of the incident light transmitted by an optical instrument or reflected by a mirror or system of mirrors, and for the measurement of the relative brightness of different parts of the field of view of an optical instrument, is described.

Optical and Infrared Photometry of the nearby SN 2017cbv [PDF]

open access: yesThe 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.

Optical Photometry of Flares and Flare Statistics [PDF]

open access: yesInternational Astronomical Union Colloquium, 1983
This review discusses optical observations of flares and the results gleaned from these. Excellent reviews of flare activity have been published in the past and one might mention in particular Kunkel (1975), Gershberg (1978) and Gurzadyan (1980). In general these have been more broadly based than the present review incorporating other aspects of flare ...

Optical and Radio Surface Photometry of NGC 891 [PDF]

open access: yesSymposium - 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.
