P22P We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3 within the L1204 molecular cloud. ... The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a. Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. ...

The black hole (BH) masses in the centers of active galactic nuclei (AGNs) have been estimated for a sample of radio-selected, flat-spectrum quasars to investigate the relationship between BH mass and radio properties of quasars. ... In contrast to previous studies, we find no correlation between BH mass and radio power in these AGNs. We find a range in BH mass similar to that seen in radio-quiet quasars from previous studies. ... You can now find me in room 99 at Epping. ...

... Study of Mg-Fe-silicate glasses of variable composition. ... With the new data, the astrophysical discussion started in Paper I was continued and focussed on the comparison of the olivine glass data with IRAS LRS spectra of O-rich circumstellar envelopes around Mira stars. ... The new olivine glasses point to the interesting consequence that the temperature for silicate dust grains at the inner edge of circumstellar envelopes must be considerably higher than the values often given in the literature....

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

... Up: Software Systems and Tools . ... This case study examines the use of the latest software techniques for merging independent Java applets and applications. STScI's new Java interface to the archive, StarView II, will make use of the ST-ECF stand-alone FITS image viewer JIPA. We discuss how state-of-the-art software techniques like Remote Method Invocation (RMI), multithreading, and the Reflection API influence the design of a common interface between StarView II and JIPA. ...

... These sources are known from a previous study to be associated with dense gas and dust, and not associated with HII regions. All 11 sources were detected in HCO+, 9 in mm-continuum and 5 (out of 8 observed) in cm-continuum. The derived physical parameters confirm the high mass nature of these molecular clumps and suggest they are gravitationally bound. Molecular outflows were detected toward 6 sources, with flow masses and momenta much higher than in low-mass Young Stellar Objects (YSOs). ...
