Journal ArticleDOI
Magnetic field of a cylindrical coil
TL;DR: In this paper, the magnetic fields of cylindrical coils due to a surface current and a volume current were calculated using a simple experimental apparatus and compared with the measured magnetic fields.
Journal ArticleDOI
The effect of dust obscuration in RR Telescopii on optical and IR long-term photometry and Fe II emission lines
Dubravka Kotnik-Karuza,Michael Friedjung,Patricia A. Whitelock,Freddy Marang,Katrina Exter,Francis P. Keenan,Don Pollacco +6 more
TL;DR: In this article, a set of photometric and spectroscopic observations of the symbiotic nova RR Tel in different wavelength bands were used to study the effects and properties of dust in symbiotic binaries containing a cool Mira component, as well as showing “obscuration events” of increased absorption, which are typical for such Miras.
Journal ArticleDOI
The effect of dust obscuration in RR Tel on optical and IR long-term photometry and Fe II emission lines
Dubravka Kotnik-Karuza,Michael Friedjung,Patricia A. Whitelock,Freddy Marang,Katrina Exter,Francis P. Keenan,Don Pollacco +6 more
TL;DR: In this paper, a set of photometric observations of the symbiotic nova RR Tel in different wavelength bands -visual from 1949 to 2002 and near-infrared (JHKL) from 1975 to 2002 -were presented.
Journal ArticleDOI
Modelling of dust around the symbiotic Mira RR Telescopii during obscuration epochs
TL;DR: In this article, a model of inner dust regions around the cool Mira component of the symbiotic nova RR Tel based on the near-IR terrestrial photometry and infrared ISO spectra was presented.
Journal ArticleDOI
The region of Fe II emission line formation of the symbiotic nova RR Telescopii
TL;DR: In this article, the authors applied the SAC method to the optical Fe II emission line fluxes measured by Crawford et al. and found that the permitted lines are formed in a region with a radius between 1:8 10 12 cm and 1:6 10 14 cm.
