Description
The IUE observed AB Aur, HD250550, and BD + 46 deg 3471 at high resolution in the range 2000 to 32000 A. The MgII resonance line profiles all show a P Cygni structure, with an intense emission, and a shortward wing velocity in the absorption component of 300 to 600 km/sec. In HD 250550, the Fe II line spectrum exhibits a shell phenomenon: all lines are blue displaced by - 290 km/sec; other lines of singly ionized species show the same effect. The mass loss rate in AB Aur estimated from an analysis of both MgII resonance lines and unsaturated Fe II multiplet 1 lines is smaller than previously reported.

    The Gravitational-wave Optical Transient Observer (GOTO)
    The Gravitational-wave Optical Transient Observer (GOTO) is a project dedicated to identifying optical counterparts to gravitational-wave detections using a network of dedicated, wide-field telescopes. After almost a decade of design, construction, and commissioning work, the GOTO network is now fully operational with two antipodal sites: La Palma

    Innovative solution for upgrading commercial bearings for use in cryogenic instruments
    Infrared instruments for astronomy require many bearings for motion that must move in cryogenic conditions. There are poor and expensive options for this, and the companies with qualified bearings only supply after a long time. To attend these constrains, the Instituto de Astrofísica de Canarias (IAC) started to develop a procedure to upgrade
