LMC far-UV HST observations
Listed in IVOA Registry (Virtual Observatory)
We present a new analysis of the deepest pure-ultraviolet (UV) observations with the highest angular resolution ever performed.
Description
A set of 12 exposures with the Hubble Space Telescope (HST) WFPC2 and F160BW filter obtained in parallel observing mode, which cover ~12arcmin^2^ in the Large Magellanic Cloud (LMC), north of the bar and in the 'general field' region of the LMC, contain stars with far-UV monochromatic magnitudes as faint as 22mag.
The 198 detected UV sources represent an accumulated exposure of 2x10^4^s and reveal stars as faint as m_UV_=~20mag. We combine these observations with deep UBVI charge-coupled device (CCD) imaging of the same region reaching as faint as V=~26mag, and reselect probable optical counterparts for the UV sources. After a two-stage search-and-analysis process, we detect robust counterparts for 129 stars.

These are mostly upper main-sequence stars, from early B to early A spectral classes, with several F stars. We point out the lack of blue supergiants, which could have been easily detected in our survey. We measure a foreground extinction E(B-V)=~0.08mag by Galactic dust and a surface density of star formation rate twice the average Galactic value.
These observations indicate that relatively recent star formation took place even off the bar of the LMC.
