AG Carinae is a massive, evolved supergiant which is thought to be in transition from an O star to a Wolf-Rayet (WR) star and is currently identified as a luminous blue variable (LBV) with logL/solar=6.0. We present an abundance study of the ejecta nebula surrounding AG Car with the aim of elucidating the evolutionary history of the central star

We present results of intermediate resolution spectroscopy of 131 optical counterparts to 115 ROSAT All-Sky Survey X-ray sources south of the Taurus-Auriga dark cloud complex. These objects have been selected as candidate young stars from a total of 1084 ROSAT sources in a ~300 square degree area. We identify 30 objects as low-mass PMS stars on the

We present one new radio identification and one confirmation of two high-latitude gamma-ray sources detected by CGRO-EGRET, based on flux density measurements at 1.3 mm (Caltech Submillimeter Observatory2) and 1.3 cm (Metsähovi Research Station) of objects in the EGRET error boxes. We identify EGRET sources 10744+5438 and J1239+044l with 87GB

Table 3 gives a catalog of HII region positions, diameters and absolute emission line logarithmic fluxes for NGC 4736. Table 4 gives a catalog of continua logarithmic fluxes adjacent to [OII], Hβ, [OIII], Hα, [SII] and [SIII] emission lines of NGC 4736 HII regions. (2 data files).

2D-FIS, a bundle of 125 optical fibres mounted in the focal plane of the WHT, has been used to study two-dimensional stellar kinematics and populations in nearby galaxies.
