... The presence of solid­state emission bands is compared to other indicators of circumstellar material, such as Hff emission, optical variability and sub­mm continuum fluxes. ... However, a strong dependence on spectral type of the central star seems to be present: stars with spectral type earlier than B9 show either amorphous silicate in absorption or infrared spectra dominated by PAH emission, whereas more than 70% of the stars of later spectral type show silicate emission. ...

This was not corrected in the figure shown in Appendix A. HS1214+3801 : This is seemingly a supergiant H II -region at the very rim of the nearby edge-on disc galaxy (SA(s)cd) NGC 4244 (V hel = 224 kms -1 and B T =10.88). ... To check this option one needs a detailed map of the NGC 4244 velocity field including HS 1214+3801. ...

. The frequency of the spectral maximum f m of the gyrosynchrotron emission vs. the power-law index of the electron spectrum calculated according to Dulk & Marsh (1982). Curves are shown for various column densities LNe of accelerated electrons and magnetic field strengths B . The angle between the line of sight and the magnetic field is 45 degree.

... Low-latitude aurorae are a storm time phenomena, in which particles originating from the ring current (and/or which are energized by the ring current) enter the lower thermosphere causing optical emission. It has been suggested (Rassoul et al., 1993) that four "pure" types of such auroras exist, as shown in table below, where LEE = low energy electron aurora, and HP = heavy particle aurora. ... low-latitude . ... One should thus not confuse them with other red emissions from much lower altitudes. ...

Pulsars (from PULSAting stARs) were discovered, albeit accidentally, by Jocelyn Bell at Cambridge in 1967. ... In addition, some pulsars are known to be members of binary systems in which the companion is another neutron star, a white dwarf and even a main sequence star. ... PSR B1913+16: . ... Although subsequent pulsar surveys with better sensitivity to short period objects have found a large number of similar objects, for 24 years PSR B1937+21 stayed as the most rapidly rotating neutron star known. ...
