Precision CCD photometry of globular clusters [PDF]
The first part of this thesis presents a review of colour-magnitude photometry of Galactic globular clusters. A survey has been made of recently-published colourmagnitude photometry of globular clusters, and a self-consistent distance scale established ...

The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect
Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.

Identifying the Photometric Characteristics and Applicability of Hybrid Solar Lighting
The present research aims at promoting the stability and applicability of a hybrid daylighting system combining daylight and artificial light, which eventually enables a constant and pleasant luminous flux of the mixed light delivered by a terminal ...

Identification of the Mixing Ratios of Beer-Mixed Beverages by UV/VIS Spectroscopy
UV/VIS spectroscopy was used in conjunction with a calibration method to determine the mixing ratio of samples of beer-mixed drinks with mineral water (sour Radler beers) from the food service industry.

Spectroscopy and multiband photometry of the afterglow of intermediate duration γ-ray burst GRB 040924 and its host galaxy [PDF]
Aims. We present optical photometry and spectroscopy of the afterglow and host galaxy of gamma-ray burst GRB040924. This GRB had a rather short duration of T90 ∼ 2.4 s, and a well sampled optical afterglow light curve.

Luminosity and photometry [PDF]
Abstract The luminosity of the spectrum was determined by what may be term ed the method of the “minimal effective stimulus.” Through the partition separating two dark rooms from each other a hole was drilled 1 mm. across; this was covered with a piece of ground glass.
