Precision CCD photometry of globular clusters
… 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 for these data, using the method of subdwarf matching to the …

Earthshine : Photometry, modeling, and spectral observations
The Earthshine group has been making sustained observations of the Earthshine from Big Bear Solar Observatory in California since late 1998. There have also been intermittent observations from 1994-5. High and low resolution Earthshine spectral observations have also been under taken at Palomar …

Photographic photometry of Magellanic Cloud cepheids
Photographic (B,V) light curves of 213 LMC and 180 SMC cepheids (and W Virginis stars) have been obtained and the relevant light-curve parameters derived. Comparison of this work with stars in common with photoelectric data indicate that the <V> and (<B> - <V>) magnitudes differ from their …

Computational starspot photometry of contact binary stars
Starspots are not well understood for contact binary star systems. The following properties of spots were systematically investigated: temperature, radius, colatitude, and longitude. Spots were modeled on an AE Phe like contact binary system. The spots were changed in a systematic manner. The light …

Exoplanet Atmospheric Characterization using High-Precision Photometry
The field of Exoplanet is rapidly maturing hour by hour. With present and future proposed telescopes, our understanding of alien worlds is going to get much more profound. The main focus of my thesis is the study of spectral signatures in Photometric observations of exoplanets both in optical and …

Extrasolar planet transit photometry at Wallace Astrophysical Observatory
Extrasolar planet transit photometry is a relatively new astronomical technique developed over the past decade. Transit photometry is the measurement of a star's brightness as an orbiting planet passes in front of the star as seen from the Earth. Recently, members of MIT's Planetary Astronomy Lab …

Time series photometry of the dwarf planet Eris
This project utilizes time series photometry to attempt to find the period of the newly discovered Kuiper Belt Object (KBO), Eris. Eris is known to have a radius slightly larger than Pluto and an extremely high albedo of 86%, indicative of fresh surface ices. This high albedo makes it likely that …

Variable star photometry in a secondary school curriculum
The author proved that photometry of variable stars can be performed by anyone using the shoestring budget of only a digital camera along with a laptop. Extrinsic variable star Algol was observed using a 14" telescope as well as CCD and had its light curve plotted. In direct comparison, V474 Mon …

Photometry and transit-timing analysis for eleven transiting exoplanets
This thesis presents time-series photometry of transits of 11 different extrasolar planets. Observations were conducted with the Fred L. Whipple Observatory 1.2m telescope and the Wise Observatory im telescope, in standard optical bandpasses. The number of transits observed for each planet ranges …

FLAME PHOTOMETRY OF PHOSPHORUS AND SULFUR BY GRAPHITE ATOMIZER VAPORIZATION
… dissertation deals with flame photometry as a method for phosphorus analysis. In a hydrogen-rich flame phosphorus atoms undergo a chemiluminescent reaction to form an excited HPO molecule, which emits with maximum intensity at 526 nm. Normally this method is used to selectivity …

Feasibility-study for space-based transit photometry using mid-sized nanosatellites
The photometric precision needed to measure a transit of small planets cannot be achieved by taking observations from the ground, so observations must be made from space. Mid-sized nanosatellites can provide a low-cost option for building an optical system to take these observations. The potential …
