The EUV transient RE J1255 + 266

The EUV transient RE J 1255

We have identiied the optical counterpart of the EUV transient source RE J1255+266 with a 18 magnitude blue star which has an unusual optical spectrum showing a blue continuum and broad Balmer absorption lines characteristic of a DA white dwarf, together with intense narrow H Balmer and He I lines in emission. Subsequent optical spectroscopy and photometry, together with near-IR photometry, dem...

Transient events in the EUV transition region and chromosphere

Rapid time cadence observations of the quiet Sun extreme ultraviolet emission, observed by the cds instrument on soho, are discussed. Numerous transient brightenings are observed in network features in both a transition region line (O v 629.73 Å) and a chromospheric line (He i 584.33 Å), indicating a dynamic coupling between the chromospheric and transition region network. Their durations are b...

Type II lesions are common lesions encountered in overhead athletes with controversies arising in term of timing for treatment, surgical approach, rehabilitation and functional results. The aim of our study was to evaluate the outcomes of arthroscopic repair of type II SLAP tears in overhead athletes, focusing on the time elapsed from diagnosis and treatment, time needed to return to sport, rat...
