Analyzing Exoplanet Survey Methods Using Massive Datasets: Transit and Microlensing Light Curves
(2020-04-03)
The light curve has taken on a new importance in the field of astrophysics in the 21st century. Next generation telescopes such as the Vera C. Rubin Observatory and the Wide Field Infrared Survey Telescope (WFIRST) will ...
A High-Performance, Catalog-Driven Approach to Light Curve Extraction for Wide-Field Photometric Surveys
(2019-07-25)
The Kilodegree Extremely Little Telescope (KELT) is an ongoing, wide-field, all-sky,
time-domain photometric survey built to discover new transiting extrasolar planets of high
scientific value orbiting bright host stars. ...
Determining the Acceleration Mechanism and Magnetic Topological Structure of Coronal Jets: Evidence for Multiple Acceleration Mechanisms
(2020-08-24)
Solar coronal jets are small-scale, energetic eruptions, characterized by a column-like spire and a bright, dome-shaped base. Jets are often associated with notable changes in the underlying photospheric magnetic field ...
Stellar Evolution at the Crossroads: Resolving the Nature of RV Tauri Variable Systems Using Unprecedented Observations From the Kepler and XMM-Newton Space Telescopes
(2021-03-16)
RV Tauri variables are luminous pulsating supergiant stars (~10^3 Lsun) with pulsation periods between ~20--150 days and extend the period--luminosity relation of Type II Classical Cepheids. In addition to pulsational ...
Finding Flybys in the Illustris Simulation
(2021-08-23)
The lifespan of a galaxy is punctuated by both mergers and flybys, yet most methods to track the galaxy assembly history within a cosmological simulation are designed to identify only mergers. Here, we present the full ...
Spectroscopic and Adaptive Optics Observations of Protostellar Magnetospheres and Binary Star Evolution
(2021-07-09)
Overall, there has been growing progress in the astrophysical literature towards the characterization of young stellar evolution phenomenon. The use of sensitive, near-infrared observations continues to unravel these ...
Developing an Accurate Probe of the Galaxy-Halo Connection: Baryonic Effects, Small-Scale Galaxy Clustering, and Halo Model Extensions
(2022-03-29)
Over the past 14 billion years, the Universe has evolved from a state of nearly uniform density into a complex web of structure. Slight perturbations in the initial density field grew over time via gravity, resulting in ...
Multiplicity Systems as Metrics for Stellar Evolution Theory: Spectroscopic Eclipsing, Eclipsing, and Unresolved Binaries
(2022-03-30)
Binary stars serve as the astrophysical laboratory in the extraction of stellar and orbital parameters and as calibration sites for stellar evolution theory. These systems come in three flavors, spectroscopic eclipsing, ...
In Search of Small Planets Around Small Stars: Conducting Photometric Transit Surveys of Nearby M-dwarfs
(2022-03-27)
M-dwarfs have the lowest mass, size, luminosity and temperature of main sequence stars and also make up the majority of the total number of stars in our Milky Way galaxy. However, since the first exoplanet systems that ...
Clusters on the Edge: The Interface Between Galaxy Cluster Outskirts and Large-Scale Intercluster Filaments
(2022-03-27)
There is a large-scale structure to the Universe, known as the cosmic web. Galaxy Clusters, consisting of hundreds to thousands of galaxies, form along and at the nodes of the cosmic filaments that make up this web. This ...
