Optical Coronagraphic Spectroscopy of AU Mic: Evidence of Time Variable Colors?

, 2017
We present coronagraphic long slit spectra of AU Mic's debris disk taken with the STIS instrument aboard the Hubble Space Telescope (HST). Our spectra are the first spatially resolved, scattered light spectra of the system's disk, which we detect at ...

The oxygen abundance deficiency in irregular galaxies [PDF]

, 2000
The observed oxygen abundances in a number of irregular galaxies have been compared with predictions of the closed-box model of chemical and photometric evolution of galaxies. Oxygen is found to be deficient with respect to the predicted abundances. This

Discovery of an extended debris disk around the F2V star HD 15745 [PDF]

, 2007
Using the Advanced Camera for Surveys aboard the Hubble Space Telescope, we have discovered dust-scattered light from the debris disk surrounding the F2V star HD 15745. The circumstellar disk is detected between 2.0" and 7.5" radius, corresponding to 128

A Multi-Epoch HST Study of the Herbig-Haro Flow from XZ Tauri

, 2008
We present nine epochs of Hubble Space Telescope optical imaging of the bipolar outflow from the pre-main sequence binary XZ Tauri. Our data monitors the system from 1995-2005 and includes emission line images of the flow. The northern lobe appears to be
