GALEX Ultraviolet photometry of NGC 2420: searching for WDs
C. De Martino, L. Bianchi, I. Pagano +2
We present color-magnitude diagrams of the open cluster NGC 2420, obtained from Galaxy Evolution Explorer (GALEX) ultraviolet images in FUV and NUV bands and Sloan Digital Sky Surv…
Statistical Properties of the GALEX/SDSS matched source catalogs, and classification of the UV sources
Luciana Bianchi, Lino Rodriguez-Merino, Maurice Viton +30
We use the Galaxy Evolution Explorer (GALEX) Medium and All-Sky-Imaging Survey (MIS & AIS) data from the first public data release (GR1), matched to the Sloan Digital Sky Survey (S…
Discovery of NeVII in the Winds of Hot Evolved Stars
J. E. Herald, L. Bianchi, J. D. Hillier
We show that a strong P-Cygni feature seen in the far-UV spectra of some very hot (Teff >~ 85 kK) central stars of planetary nebulae (CSPN), which has been previously identified as…
Central Stars of Planetary Nebulae in the Large Magellanic Cloud: A Far-UV Spectroscopic Analysis
J. E. Herald, L. Bianchi
We observed seven central stars of planetary nebulae (CSPN) in the Large Magellanic Cloud (LMC) with the Far Ultraviolet Spectroscopic Explorer (FUSE), and performed a model-based…
Far-UV Spectroscopic Analyses of Four Central Stars of Planetary Nebulae
J. E. Herald, L. Bianchi
We analyze the Far-UV/UV spectra of four central stars of planetary nebulae with strong wind features -- NGC 2371, Abell 78, IC 4776 and NGC 1535, and derive their photospheric and…
A Far-UV Spectroscopic Analysis of the Central Star of the Planetary Nebula Longmore 1
J. E. Herald, L. Bianchi
We have performed a non-LTE spectroscopic analysis using far-UV and UV data of the central star of the planetary nebula K1-26 (Longmore 1), and found Teff = 120+/-10 kK, logg = 6.7…
