Mass-to-Light versus Color Relations for Dwarf Irregular Galaxies
Kimberly A. Herrmann, Deidre A. Hunter, Hong-Xin Zhang +1
We have determined new relations between colors and mass-to-light ratios () for dwarf irregular (dIrr) galaxies, as well as for transformed . These…
Non-Vestoid candidate asteroids in the inner main belt
Dagmara Oszkiewicz, Brian A. Skiff, Nick Moskovitz +5
Most Howardite-Eucrite-Diogenite (HED) meteorites (analogs to V-type asteroids) are thought to originate from asteroid (4) Vesta. However, some HEDs show distinct oxygen isotope ra…
A 16-Year Photometric Campaign on the Eclipsing Novalike Variable DW Ursae Majoris
D. R. S. Boyd, E. de Miguel, J. Patterson +29
We present an analysis of photometric observations of the eclipsing novalike variable DW UMa made by the CBA consortium between 1999 and 2015. Analysis of 372 new and 260 previousl…
Outskirts of Nearby Disk Galaxies: Star Formation and Stellar Populations
Bruce G. Elmegreen, Deidre A. Hunter
The properties and star formation processes in the far-outer disks of nearby spiral and dwarf irregular galaxies are reviewed. The origin and structure of the generally exponential…
Post-common envelope PN, fundamental or irrelevant?
Orsola De Marco, T. Reichardt, R. Iaconi +6
One in 5 planetary nebulae are ejected from common envelope binary interactions but Kepler Space Telescope results are already showing this proportion to be larger. Their propertie…
Physical Characterization of ~2-meter Diameter Near-Earth Asteroid 2015 TC25: A possible boulder from E-type Asteroid (44) Nysa
Vishnu Reddy, Juan A. Sanchez, William F. Bottke +11
Small near-Earth asteroids (>20 meters) are interesting because they are progenitors for meteorites in our terrestrial collection. Crucial to our understanding of the effectiveness…
