A High-Resolution Study of the HI Content of Local Group Dwarf Irregular Galaxy WLM
Amanda Kepley, Eric Wilcots, Deidre Hunter +1
Dwarf irregular galaxies are unique laboratories for studying the interaction between stars and the interstellar medium in low mass environments. We present the highest spatial res…
Initial Results from the USNO Dispersed Fourier Transform Spectrograph
Arsen R. Hajian, Bradford B. Behr, Andrew T. Cenko +15
We have designed and constructed a ``dispersed Fourier Transform Spectrometer'' (dFTS), consisting of a conventional FTS followed by a grating spectrometer. By combining these two…
DDO 43: A Prototypical Dwarf Irregular Galaxy?
Caroline E. Simpson, Deidre A. Hunter, Tyler E. Nordgren
We present sensitive and high resolution 21 cm observations of the dwarf irregular (dIm) galaxy DDO 43, in conjunction with optical broad and narrow band images in U, B, V, and Hal…
Predicted and empirical radii of RR Lyrae stars
M. Marconi, T. Nordgren, G. Bono +2
We present new theoretical Period-Radius-Metallicity (PRZ) relations for RR Lyrae stars. Current predictions are based on a large set of nonlinear, convective models that cover a b…
Asymmetric Surface Brightness Distribution of Altair Observed with the Navy Prototype Optical Interferometer
Naoko Ohishi, Tyler E. Nordgren, Donald J. Hutter
An asymmetric surface brightness distribution of the rapidly rotating A7IV-V star, Altair, has been measured by the Navy Prototype Optical Interferometer (NPOI). The observations w…
Theoretical Limb Darkening for Classical Cepheids: II. Corrections for the Geometric Baade-Wesselink Method
Massimo Marengo, Margarita Karovska, Dimitar D. Sasselov +2
The geometric Baade-Wesselink method is one of the most promising techniques for obtaining a better calibration of the Cepheid period-luminosity relation by means of interferometri…
