The ELM Survey. II. Twelve Binary White Dwarf Merger Systems
We describe new radial velocity and X-ray observations of extremely low-mass white dwarfs (ELM WDs, ~0.2 M sun) in the Sloan Digital Sky Survey Data Release 4...
The ELM Survey. III. A Successful Targeted Survey for Extremely Low Mass White Dwarfs
Extremely low mass (ELM) white dwarfs (WDs) with masses 0.25 M &sun; are rare objects that result from compact binary evolution. Here, we present a targeted...
We present new radial velocity and X-ray observations of extremely low mass (ELM, ~0.2 M &sun;) white dwarf (WD) candidates in the Sloan Digital Sky Survey Data...
The ELM Survey. VII. Orbital Properties of Low-Mass White Dwarf Binaries
We present the discovery of 15 extremely low-mass (5\lt {log}g\lt 7) white dwarf (WD) candidates, 9 of which are in ultra-compact double-degenerate binaries...
The Emission and Distribution of Dust of the Torus of NGC 1068
We present observations of NGC 1068 covering the 19.7–53.0 μm wavelength range using FORCAST and HAWC+ on board SOFIA. Using these observations, high-angular...
The Evershed Effect Observed with 0.2" Angular Resolution
We present an analysis of the Evershed effect observed with a resolution of 0.2". Using the new Swedish 1 m Solar Telescope and its Littrow spectrograph, we...
