An XMM-Newton study of the RGH 80 galaxy group
Böhringer, H.; Matsushita, K.; Xue, Y. -J.
We present an X-ray study of the galaxy group RGH 80, observed by XMM-Newton. The X-ray emission of the gas is detected out to ∼462 h-150 kpc, corresponding to ∼0.45 r200. The group is relatively gas rich and luminous with respect to its temperature of 1.01 ± 0.01 keV. Using the deprojected spectral analysis, we fi…

Deep Photometry in a Remote M31 Major-Axis Field Near G1
Ho, Luis C.; Gebhardt, Karl; Rich, R. Michael +2 more
We present photometry from Hubble Space Telescope (HST) Wide Field Planetary Camera 2 parallel imagery of a remote M31 field at a projected distance of ~34 kpc from the nucleus near the southwest major axis. This field is near the globular cluster G1, and near one of the candidate tidal plumes identified in the survey of Ferguson et al. (2002). Th…

The XMM-Newton view of the X-ray halo and jet of NGC 6251
Cheung, C. C.; Tavecchio, F.; Mushotzky, R. F. +3 more
We present an XMM-Newton observation of the radio jet and diffuse halo of the nearby radio galaxy NGC 6251. The EPIC spectrum of the galaxy's halo is best-fitted by a thermal model with temperature kT ∼ 1.6 keV and sub-solar abundances. Interestingly, an additional hard X-ray component is required to fit the EPIC spectra of the halo above 3 keV, a…
WIYN Open Cluster Study. XIX. Main-Sequence-Fitting Distances to Open Clusters Using V-K Color-Magnitude Diagrams
Sarajedini, Ata; Brandt, Ken; Grocholski, Aaron J. +1 more
We have combined existing optical magnitudes for stars in seven open clusters and 54 field stars with the corresponding JHKs photometry from the Two Micron All Sky Survey (2MASS). Combining optical with near-IR photometry broadens the color baseline, minimizing the influence of photometric errors and allowing better discrimination betwe…
The evolution and simulation of the outburst from XZ Tauri - A possible EXor?
Ray, T. P.; Coffey, D.; Downes, T. P.
We report on multi-epoch HST/WFPC2 images of the XZ Tauri binary, and its outflow, covering the period from 1995 to 2001. Data from 1995 to 1998 have already been published in the literature. Additional images, from 1999, 2000 and 2001 are presented here. These reveal not only further dynamical and morphological evolution of the XZ Tauri outflow b…
Two examples of magnetic clouds with double rotations observed by the Ulysses spacecraft
Forsyth, R. J.; Rees, A.
A survey of Ulysses magnetometer data has been carried out between Oct 1990 (launch) and Apr 2003 (just after the second northern polar pass) cataloguing magnetic cloud (MC) signatures, i.e., a smooth magnetic field rotation and enhanced magnetic field magnitude. After confirming that each of these events was a true MC by checking for a low proton…

Molecular Hydrogen Emission Lines in Far Ultraviolet Spectroscopic Explorer Observations of Mira B
Wood, Brian E.; Karovska, Margarita
We present new Far Ultraviolet Spectroscopic Explorer (FUSE) observations of Mira A's wind-accreting companion star, Mira B. We find that the strongest lines in the FUSE spectrum are H2 lines fluoresced by H I Lyα. A previously analyzed Hubble Space Telescope (HST) spectrum also shows numerous Lyα-fluoresced H2 lines. The HST…
