We present the results of a photometric and spectroscopic survey of cool M dwarf candidates in the young open cluster NGC 2547. Using the 2dF fiber spectrograph, we have searched for the luminosity at which lithium remains unburned in an attempt to c... Read More about The lithium depletion boundary and the age of NGC 2547.

The host galaxy of GRB010222: the strongest damped Lyman-alpha system known (2001)
Journal Article
Maxted, P. (2001). The host galaxy of GRB010222: the strongest damped Lyman-alpha system known

Analysis of the absorption lines in the afterglow spectrum of the gamma-ray burst GRB010222 indicates that its host galaxy (at a redshift of z=1.476) is the strongest damped Lyman-alpha (DLA) system known, having a very low metallicity and modest dus...

Emission from the secondary star in the old CV WZ Sge (2001)
Journal Article
Maxted. (2001). Emission from the secondary star in the old CV WZ Sge. Astrophysical Journal, 145-148. https://doi.org/10.1086/338107

We present the first detection of the mass donor star in the cataclysmic variable WZ Sge. Phase resolved spectroscopy reveals narrow Balmer emission components from the irradiated secondary star during the 2001 outburst. Its radial velocity curve ind...

Ages, distances, and the initial mass functions of stellar clusters (2000)
Journal Article
Jeffries, R. (2000). Ages, distances, and the initial mass functions of stellar clusters. arXiv,

We provide a review of the current status of several topics on the ages, distances, and mass functions of open clusters, with a particular emphasis on illuminating the areas of uncertainty. Hipparcos has obtained parallaxes for nearby open clusters t... Read More about Ages, distances, and the initial mass functions of stellar clusters.

Outflows from galaxy nuclei: dynamics and implications for scaling relations
Thesis
Outflows from galaxy nuclei: dynamics and implications for scaling relations. https://keele-repository.worktribe.com/output/404176

The M–s relations observed between the masses of central massive objects (CMOs: either a nuclear star cluster or a supermassive black hole) in galaxy nuclei and the stellar velocity dispersion of their host galaxy bulges strongly suggest that the evo...

This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries.

Part I investigates kinematical biases between two methods of... Read More about Fundamental Properties of Solar-Type Eclipsing Binary Stars, and Kinematic Biases of Exoplanet Host Stars.

Studies of cosmic dust analogues using synchrotron X-ray powder diffraction
Thesis
Studies of cosmic dust analogues using synchrotron X-ray powder diffraction. https://keele-repository.worktribe.com/output/405117

The structural evolution of cosmic dust analogues has been investigated using in situ synchrotron X-ray powder diffraction (SXPD) at the Diamond Light Source. Amorphous Mg/Ca silicates are produced as analogues of cosmic dust using a modified sol-gel... Read More about Studies of cosmic dust analogues using synchrotron X-ray powder diffraction.

Evolution of electron capture supernova progenitors: new models, improved nuclear physics and hydrodynamic mixing uncertainties
Thesis
Evolution of electron capture supernova progenitors: new models, improved nuclear physics and hydrodynamic mixing uncertainties. https://keele-repository.worktribe.com/output/405119

Electron capture supernovae (EC-SNe) are the deaths of approximately 8-10M stars. In this thesis, the evolution of 8-12M stars is calculated using the MESA stellar evolution code. The aims of this thesis are to produce the most advanced and up-to-dat...

Probing the diffuse interstellar medium with diffuse interstellar bands
Thesis
Probing the diffuse interstellar medium with diffuse interstellar bands. https://keele-repository.worktribe.com/output/405172

This work investigates the small scale structure of the Diffuse Interstellar Medium. To do this optical spectroscopy is used to obtain spectra of early type stars which are used as background targets with which the Diffuse Interstellar Medium (ISM) i...

Starspot properties and photometric parameters of transiting planets and their host stars
Thesis
Starspot properties and photometric parameters of transiting planets and their host stars. https://keele-repository.worktribe.com/output/405331

To begin understanding how the architecture of hot Jupiter planetary systems can be so radically different from that of our own solar system, requires the dynamical evolution of planets to be known. By measuring the sky-projected obliquity ? of a sys... Read More about Starspot properties and photometric parameters of transiting planets and their host stars.

A survey for pulsations in A-type stars using SuperWASP
Thesis
A survey for pulsations in A-type stars using SuperWASP. https://keele-repository.worktribe.com/output/405697

A survey of A-type stars is conducted with the SuperWASP archive in the search for pulsationally variable stars. Over 1.5 million stars are selected based on their (J - H) colour. Periodograms are calculated for light curves which have been extracted... Read More about A survey for pulsations in A-type stars using SuperWASP.

Identifying and characterising young, nearby, low-mass members of stellar moving groups
Thesis
Binks, A. S. Identifying and characterising young, nearby, low-mass members of stellar moving groups. https://keele-repository.worktribe.com/output/407043

Since the early 1990s, several groups of comoving, coeval stars younger than 100Myr and within 100 pc have been revealed. Studying and identifying members in these ‘Nearby Young Moving Groups’ (MGs) is vital because they provide: well characterised s...

Mahtani, D. P. Spitzer Space Telescope observations of hot Jupiters. https://keele-repository.worktribe.com/output/407058

Currently the Spitzer Space Telescope is the most reliable telescope for conducting secondary eclipse observations of exoplanets. The depth and the time of mid-eclipse are two important parameters that come from a secondary eclipse analysis. The ecli... Read More about Spitzer Space Telescope observations of hot Jupiters.

Thesis
Dobson, A. Kinematics and age spreads of the young star-forming region NGC 2264. https://keele-repository.worktribe.com/output/407163

While stars are relatively well understood, the timescales on which they form are still debated. The young cluster NGC 2264 is an ideal region in which to test hypotheses about the timescale of star and cluster formation. Co-eval stars at any given e...
