Co-Spatial UV-Optical HST/STIS Spectra of Seven Galactic Planetary Nebulae: Nebular and Stellar Properties
Miller, Timothy (2017)This project had two main goals: (1) to investigate to what extent planetary nebulae (PNe) are chemically homogeneous; and (2) to provide physical constraints on the central star properties of each PN. The first goal was ... -
Comparison of the period finding algorithms on white dwarf binaries in the Zwicky Transient Facility (ZTF) Data Release 3
Catmabacak, Onder (2023-04-17)Irregular time series arise in most ground-based astronomical surveys due to atmospheric effects, missing observations, and instrumental issues that create erratic time intervals among data points and reduce data quality. ... -
COSMOLOGY WITH TYPE IA SUPERNOVAE: ROBUST TECHNIQUES FOR DATA ANALYSIS AND PHOTOMETRIC CLASSIFICATION
Dai, Mi (2017-05)Since the accelerating expansion of the Universe was discovered by observing distant Type Ia supernovae (SNe Ia), SNe Ia have been playing an important role in constraining the unknown cause behind the observed cosmic ... -
Discovery and Classification of New Circumstellar Disks from the AllWISE Catalog with Disk Detective
Silverberg, Steven (2019)In its five years since launch, DiskDetective.org has led to many new discoveries in the field of circumstellar disks. In my dissertation, I present two major emphases of the project: statistical characterization of infrared ... -
Dust Formation and Destruction in Core Collapse Supernovae Explosions
Stangl, Sarah (2024)Dust is a crucial component of the Interstellar Medium (ISM) and an important driver in many astrophysical processes. Dust formed from evolved stars increases the metallicity of the ISM, enriching it with heavier elements. ... -
Dwarf galaxies in N-body+SPH simulations
Van Nest, Jordan (2023-12)I present a study of various dwarf galaxies from N-body+SPH simulations in Lambda Cold Dark Matter cosmology. While the science results of this thesis pertain to dwarf galaxies of varying classifications and environments, ... -
Evolution and Stability of Ultra-Wide Trans-Neptunian Binaries
Campbell, Hunter (2023-08-04)This research is focused around the longevity and formation of a class of binaries in the Kuiper Belt called Ultra-Wide Trans-Neptunian Binaries (Ultra-Wide TNBs). The presence of these seemingly fragile binary systems ... -
Financial Operational Losses in Space Launch
Boone, Tom (2017-05-12)The high cost of access to space has been a problem since the beginning of the space age. Most attempts to reduce this cost are centered on improvements to launch vehicle design. While this approach has been fruitful, ... -
Galaxy Clusters Across the Electromagnetic Spectrum
Griffin, Rhiannon (2016-12)Galaxy clusters are the largest gravitationally bound objects in the Universe. From radio to X-ray, we have observed these objects across the electromagnetic spectrum. Formation theories suggest that clusters even emit ... -
A High Cadence Study of Stellar Variability: Searching for Habitable Planetary Companions Orbiting White Dwarfs with the DECam Minute Cadence Survey
Dame, Kyra (2019-07)One outstanding question in astronomy is what happens to planetary systems as their host star evolves. Though indirect evidence such as metal polluted white dwarf atmospheres and debris disks around white dwarfs, and recent ... -
The Initial-Final Mass Relation Revisited: A Monte Carlo Approach with the Addition of the M67 White Dwarf Population
Canton, Paul (2018-12)The initial-final mass relation (IFMR) describes how the initial mass of a stellar object maps to its mass as a remnant. The focus of this work is to re-examine this relation for low to intermediate mass stars. Studies ... -
Modeling Stellar Surface Features with High-Precision Photometry
Schutte, Maria (2023)Starspots are a major source of stellar contamination in transmission spectroscopy of exoplanet atmospheres, and the correction for exoplanet analyses depends on the temperature of the starspots and the covering fraction. ... -
PLANETARY REMNANTS AROUND WHITE DWARF STARS
Barber, Sara (2015-05-08)In this dissertation we present the results of four separate searches for infrared excess emission at white dwarf stars. Using spectra from the IRTF and photometry from PAIRITEL, MMT+SWIRC, Gemini+NIRI, and Spitzer+IRAC ... -
The Search for White Dwarf Binaries in Astronomical Survey Data
Kosakowski, Alekzander (2021-07-23)Extremely low mass (ELM) white dwarfs are excellent laboratories for studying a variety of astrophysical phenomena, including common-envelope evolution, gravitational wave emission, and merger physics. A significant amount ... -
Spectrum Formation at Late Times in Type Ia Supernovae
Friesen, Brian (2015-05-08)I present a study of radiative transfer effects in type Ia supernovae ranging from 3-4 months to nearly 2 years post-maximum light. I explore several components of spectrum formation, beginning with a semi-analytic model ... -
An Ultraviolet Survey of the DA White Dwarf Population of the Galaxy
Wall, Renae E. (2023-08-04)DA white dwarfs are the most common type of white dwarf in our Galaxy. Hence, it is important to study the DA white dwarf population as thoroughly as possible. In this dissertation, I present our work using the Galaxy ...
