  • The Devil Star: Analyzing Data from the Massive Magnetic Star HD66665 

    Adams, Brooke
    The magnetic massive star named tau Sco (Fig. 1) was unique with its unusually complex magnetic field until two other stars were discovered with similar light spectra, HD63425 and HD66665 (aka the “Devil star”). Dr. Petit ...
  • Spectral Properties of Lunar Impact Melt Flows 

    Eaton, Charlotte
    The Moon is in synchronous rotation with the Earth. This means that the side we observe is always facing us. That side has a darker region called the mare. The mare is more enriched in iron and is believed to be solidified ...
  • Charge Injector Card for Calibration of the CMS Hadron Calorimeter 

    Schmelzle, Robert; Pelc, Alexander
    The Charge Injector Card simulates the response of the CMS Hadron Calorimeter (HF) sensors by injecting pulses of charge into the readout in the range of 3 fC to 330 pC.
  • The Magnetic Field of Theta1 Orionis C 

    Fatta, Nicholas
    θ1 Orionis C is an O type star found in the Orion Nebula. An O type star on the main sequence is 15 to 90 times more massive than the sun, and has a surface temperature between 30,000 and 50,000 K. These massive stars were ...
  • Sand Dune Elevations on the Earth, Mars, and Titan 

    Fey, Deirdra
    Sand dunes are observed on many places in the solar system. They are found on bodies with atmospheres and are formed through wind processes. Dunes can tell us about the geological process on the planets they inhabit. Dunes ...
  • Roll Differential Imaging for PSF Suppression and High-Contrast Ratios 

    Lowing, Nicholas
    Many of the most fascinating inquiries within modern astrophysics currently require the creation of new, more advanced data collection techniques that are capable of resolving issues produced by extreme contrast ratios ...
  • The Masses and Orbits of the Moons of Dwarf Planet Haumea 

    MacDonald, Mariah
    Outside of Neptune's orbit, near Pluto, lies the dwarf planet Haumea, one of the most interesting bodies ever discovered. Its triaxial ellipsoid shape implies a very fast rotation, and it has two large moons, named Hi'iaka ...
  • Measuring Unique Structures Within Sprite Halos 

    Morrison, Michael; Kosar, Burcu; Spiva, Nicholas
    Transient luminous events (TLEs) are electric discharges that occur above thunderclouds and have been categorized into several classes: elves, halos, sprites, and jets. Sprites and halos are TLEs caused by a similar ...
  • Statistical Evaluation of Simulated Period Distributions of Exoplanets Using Julia 

    Sawant, Sailee
    NASA launched the Kepler Space Telescope in March 2009 to observe the Cygnus-Lyra star field and search for Earth-like planets orbiting other stars in a habitable zone. Kepler has discovered and gathered data about thousands ...
  • Locating Supernovae via Artificial Neural Networks 

    Shahady, Kristin
    The rate at which supernova occur at large distances with high redshifts is hard to obtain. New data collection would require several hundred orbits on the Hubble Space Telescope (HST). However, there are enough HST images ...
  • SX Phoenicis Stars 

    Shuda, Suzanne
    SX Phoenicis stars are usually found in the outer regions of the galaxy which is called galactic halo. Their luminosity varies with a period of 1-2 hours. They are interesting because they are very old but have not become ...
  • Separating Near-Object Spectra From Chandra Grating Observations 

    Smith, Max
    A vast amount of knowledge about stars comes from observing their spectra in the x-ray wavelengths; however, when there are multiple stars in close proximity, such as in binary systems or clusters, reading these spectra ...
