New Stars and telescopes: Nova research in the last four centuries
Autor: Hilmar W. Duerbeck
Publikováno v: Astronomische Nachrichten. 330:568-573
This article gives a brief overview of 400 years of research in the field of novae and related stars. Important objects, first applications of various observing techniques, and early ideas of the interpretation of phenomena are listed. Also, the hist

Radial Velocity Studies of Southern Close Binary Stars. I. Winter Systems
Autor: Hilmar W. Duerbeck, Slavek M. Rucinski
Publikováno v: The Astronomical Journal. 132:1539-1546
Radial velocity measurements and sine-curve fits to the orbital velocity variations are presented for nine contact binaries: V1464 Aql, V759 Cen, DE Oct, MW Pav, BQ Phe, EL Aqr, SX Crv, VZ Lib, and GR Vir. For the first five of these, our observation

On the δ Scuti star in the eclipsing binary WX Eridani
Autor: C. Sterken, Enrique Garcia-Melendo, Hilmar W. Duerbeck, Torben Arentoft, P. van Cauteren, Patricia Lampens
Publikováno v: Astronomy & Astrophysics. 418:249-254
WX Eri is an eclipsing binary system for which one component was reported to show δ Scuti type pulsations with periods close to integer fractions of the orbital period. This makes it an interesting candidate for investigating the interaction be- twe

Sakurai's Object (V4334 Sgr): evolution of the dust shell from 1999 to 2001
Autor: A. Evans, Barry Smalley, S. P. S. Eyres, V. H. Tyne, Hilmar W. Duerbeck, Thomas R. Geballe
Publikováno v: Monthly Notices of the Royal Astronomical Society. 334:875-882
We present fits to 1–5 μm spectra of the dust shell around Sakurai's Object (V4334 Sgr) obtained over the period 1999 May to 2001 September, using the dusty modelling program. We find that the emission is consistent with carbon dust grains for whi
