The ROSAT Deep Survey IV. A distant lensing cluster of galaxies with a bright arc
G. Hasinger, R. Giacconi, J. E. Gunn +7
An unusual double-lobed extended X-ray source (RX J105343+5735) is detected in the ROSAT ultra-deep HRI image of the Lockman Hole. The angular size of the source is 1.7 X 0.7 arcmi…
Li I enhancement during a long-duration stellar flare
David Montes, Lawrence W. Ramsey
We report the possible detection of a Li I 6708 AA line enhancement during an unusual long-duration optical flare in the recently discovered, X-ray/EUV selected, chromospherically…
Multiwavelength optical observations of the chromospherically active binary system MS Ser
J. Sanz-Forcada, D. Montes, M. J. Fernandez-Figueroa +2
We present here a continuation of our ongoing project of multiwavelength optical observations aimed at studying the chromosphere of active binary systems using the information prov…
