Investigating the High-energy Radiation Environment of Planets in Sun-like Binary Systems
Patrick R. Behr, Kevin France, Nicholas Kruczek +6
Far-ultraviolet (FUV) radiation is a driving source of photochemistry in planetary atmospheres. Proper interpretation of atmospheric observations requires a full understanding of t…
The assembly, characterization, and performance of SISTINE
Nicholas Nell, Kevin France, Nicholas Kruczek +6
The Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars (SISTINE) is a rocket-borne ultraviolet (UV) imaging spectrograph designed to…
FLUID: A rocket-borne pathfinder instrument for high efficiency UV band selection imaging
Nicholas Nell, Nicholas Kruczek, Kevin France +3
The Far- and Lyman-Ultraviolet Imaging Demonstrator (FLUID) is a rocket-borne arcsecond-level ultraviolet (UV) imaging instrument covering four bands between 92 -- 193 nm. FLUID wi…
The Radiation Environments of Middle-Aged F-Type Stars
F. Cruz Aguirre, K. France, N. Nell +5
Far ultraviolet (FUV) emission lines from dwarf stars are important driving sources of photochemistry in planetary atmospheres. Properly interpreting spectral features of planetary…
High Efficiency Echelle Gratings for the Far Ultraviolet
Nicholas Kruczek, Drew M. Miles, Brian Fleming +4
Modern grating manufacturing techniques suffer from inherent issues that limit their peak efficiencies. The anisotropic etching of silicon facilitates the creation of custom gratin…
Generating Electron Beam Lithography Write Parameters from the FORTIS Holographic Grating Solution
Mackenzie Carlson, Stephan McCandliss, Randall McEntaffer +3
The Far-UV Off Rowland-circle Telescope for Imaging and Spectroscopy (FORTIS) has been successful in maturing technologies for carrying out multi-object spectroscopy in the far-UV,…
Revisiting the Temperature of the Diffuse ISM with CHESS Sounding Rocket Observations
Nicholas Kruczek, Kevin France, Keri Hoadley +2
Measuring the temperature and abundance patterns of clouds in the interstellar medium (ISM) provides an observational basis for models of the physical conditions within the clouds,…
Advanced Environmentally Resistant Lithium Fluoride Mirror Coatings for the Next-Generation of Broadband Space Observatories
Brian Fleming, Manuel Quijada, John Hennessy +7
Recent advances in the physical vapor deposition (PVD) of protective fluoride films have raised the far-ultraviolet (FUV: 912-1600 Å) reflectivity of aluminum-based mirrors closer…
Signatures of Hot Molecular Hydrogen Absorption from Protoplanetary Disks: I. Non-thermal Populations
Keri Hoadley, Kevin France, Nicole Arulanantham +2
The environment around protoplanetary disks (PPDs) regulates processes which drive the chemical and structural evolution of circumstellar material. We perform a detailed empirical…
H Fluorescence in M Dwarf Systems: A Stellar Origin
Nicholas Kruczek, Kevin France, William Evonosky +7
Observations of molecular hydrogen (H) fluorescence are a potentially useful tool for measuring the H abundance in exoplanet atmospheres. This emission was previously obser…
The re-flight of the Colorado high-resolution Echelle stellar spectrograph (CHESS): improvements, calibrations, and post-flight results
Keri Hoadley, Kevin France, Nicholas Kruczek +7
In this proceeding, we describe the scientific motivation and technical development of the Colorado High-resolution Echelle Stellar Spectrograph (CHESS), focusing on the hardware a…
Rapid Mass Segregation in Massive Star Clusters
Stephen McMillan, Enrico Vesperini, Nicholas Kruczek
Several dynamical scenarios have been proposed that can lead to prompt mass segregation on the crossing time scale of a young cluster. They generally rely on cool and/or clumpy ini…
CIV Emission and the Ultraviolet through X-ray Spectral Energy Distribution of Radio-Quiet Quasars
Nicholas E. Kruczek, Gordon T. Richards, S. C. Gallagher +6
In the restframe UV, two of the parameters that best characterize the range of emission-line properties in quasar broad emission-line regions are the equivalent width and the blues…
Unification of Luminous Type 1 Quasars through CIV Emission
Gordon T. Richards, Nicholas E. Kruczek, S. C. Gallagher +6
Using a sample of 30,000 quasars from SDSS-DR7, we explore the range of properties exhibited by high-ionization, broad emission lines, such as CIV 1549. Specifically we investigate…
