Brown dwarfs: the bridge between stars and planets
Brown dwarfs are objects with masses, effective temperatures and luminosities intermediate between those of very low-mass stars and the most massive giant...
Bulge morphology of non-interacting starburst galaxies.
The authors show, in NGC 4736, that the bulge indicates strong and radially variable ellipticity, evidence of star formation, and outflow, while the bulge of...
Bulges of Disk Galaxies at Intermediate Redshifts: Nuclear Densities and Colours
We analyze central surface brightness, nuclear and global colors of intermediate redshift disk galaxies in WFPC2/HST Groth strip and ACS/HST GOODS-N. The aim is...
Muon telescopes can have several applications, ranging from astrophysical to solar-terrestrial interaction studies, and fundamental particle physics. We show...
Burst-only sources: probing type I X-ray bursters at low persistent luminosities
The Wide Field Cameras onboard BeppoSAX observed 9 type I X-ray bursters without detectable persistent emission around the burst. According to the standard...
BVI and RV curves of 5 eclipsing binaries (Szalai+, 2007)
We detected tertiary components of close binaries from spectroscopy and light curve modelling, investigated the light-travel time effect and the possibility of...
