We have imaged the planetary nebula (PN) NGC 246 in the wavelengths [Ne V] 342.6 nm, O III at 344.4 nm, and a nearby line-free region at 338.6 nm, as well as H...
The Structure and Star-Formation History of NGC 5461
We compute photoionization models for the giant extragalactic H II region NGC 5461, and compare their predictions to several observational constraints. The...
Spectroscopic observations during a low state of BB Dor reveal a complex emission distribution. Irradiation by the white dwarf as well as magnetic fields of the...
The structure of the barred galaxy NGC253: target of the VISTA and VST Science Verification extragalactic mini-survey.
The Sculptor Galaxy NGC253 is a nearby barred Sc galaxy seen nearly edge-on and it has been the target of the Science Verification (SV) for the new ESO survey...
The Structure of the Stellar Hosts in Blue Compact Dwarf Galaxies
The structural parameters of the low surface brightness stellar host in Blue Compact Dwarf galaxies are often studied by fitting R1/n models to the outer...
The structure of the Sun. Sixth Canary Islands Winter School of Astrophysics
In this timely volume, the editors present eight specially-written chapters by experts renowned for their teaching skills. The chapters show how astronomers can...
The Structure of the Underlying Stellar Host in Blue Compact Dwarf Galaxies
Nowadays it is well established that BCDs are mostly old systems, as the vast majority of them have an extended low-surface brightness (LSB) stellar host...
