The Halos and Environments of Nearby Galaxies (HERON) I: Imaging, Sample Characteristics, and Envelope Diameters
R. Michael Rich, Aleksandr Mosenkov, Henry Lee-Saunders +16
We use a dedicated 0.7-m telescope to image the halos of 119 galaxies in the Local Volume to mag/arcsec. The sample is primarily from the 2MASS Large Galaxy At…
The Spectral Types of White Dwarfs in Messier 4
D. Saul Davis, Harvey B. Richer, R. Michael Rich +2
We present the spectra of 24 white dwarfs in the direction of the globular cluster Messier 4 obtained with the Keck/LRIS and Gemini/GMOS spectrographs. Determining the spectral typ…
The White Dwarf Cooling Sequence of NGC6397
Brad M. S. Hansen, Jay Anderson, James Brewer +10
We present the results of a deep Hubble Space Telescope (HST) exposure of the nearby globular cluster NGC6397, focussing attention on the cluster's white dwarf cooling sequence. Th…
The white dwarf cooling sequence in NGC 6791
L. R. Bedin, M. Salaris, G. Piotto +5
In the old, populous, and metal-rich open cluster NGC 6791 we have used deep HST/ACS images to track the white dwarf cooling sequence down to m_F606W~28.5. The white dwarf luminosi…
Detection of the Main Sequence Turn-off of a Newly Discovered Milky Way Halo Structure in the Triangulum-Andromeda Region
Steven R. Majewski, James C. Ostheimer, Helio J. Rocha-Pinto +3
An upper main sequence (MS) and main-sequence turn-off (MSTO) feature appears in the color-magnitude diagram (CMD) of a large area photometric survey of the southern half of M31 st…
