The kinetic temperature of a molecular cloud at redshift 0.7: Ammonia in the gravitational lens B0218+357
C. Henkel, N. Jethava, A. Kraus +6
Using the Effelsberg 100-m telescope, absorption in the (J,K) = (1,1), (2,2) and (3,3) inversion lines of ammonia (NH_3) was detected at a redshift of z = 0.6847 toward the gravita…
Zeeman tomography of magnetic white dwarfs II. The quadrupole-dominated magnetic field of HE 1045-0908
F. Euchner, K. Reinsch, S. Jordan +2
We report time-resolved optical flux and circular polarization spectroscopy of the magnetic DA white dwarf HE 1045-0908 obtained with FORS1 at the ESO VLT. Considering published re…
Distribution of magnetically confined circumstellar matter in oblique rotators
O. Preuss, M. Schuessler, V. Holzwarth +1
We consider the mechanical equilibrium and stability of matter trapped in the magnetosphere of a rapidly rotating star. Assuming a dipolar magnetic field and arbitrary inclination…
Decline of the space density of quasars between z=2 and z=4
M. Vigotti, R. Carballo, C. R. Benn +5
We define a new complete sample of 13 optically-luminous radio quasars M_AB(1450 Angstrom) < -26.9 mag and log P_1.4 GHz(W/Hz) > 25.7 with redshift 3.8 < z < 4.5, obtained by cross…
X-Ray Bursts and Proton Captures Close to the Dripline
T. Rauscher, F. Rembges, H. Schatz +2
The hydrogen-rich accreted envelopes of neutron stars in binary systems are the site for the rapid proton capture nucleosynthethic process (rp-process), which involves nuclei close…
