Using CCD observations in the narrow band filters in Hα , Hβ , [O Ii], [O Iii], [S Ii] and [S Iii] lines we have compiled a catalogue of 338 H Ii regions for the inner parts of NGC 5457 and 158 for NGC 4395. The extinction, equivalent widths, distributions, excitations, ionization hardness, ionization parameters and metallicities for these regions

We have found a large amount of 6Li in the atmosphere of the star HD 82943 which harbors two planets. From the amount of lithium in the star's atmosphere, we infer that there was a third planet (or several planets) that died in the hot interior of the star. The star could have swallowed a planet with a mass of about 2 Jupiters or 3 Earths. Based on

We will report the results from an occultation of P126A by Pluto on the night of 2002 July 20 UT. The event was successfully observed with a 0.4-m telescope at Mamiña, Chile under photometric conditions. Additional data were collected at CTIO on a 0.6-m telescope with heavy interference from clouds. The CTIO observations preclude an occultation at

We report on Chandra ACIS-S observations of five type I X-ray bursters with low persistent emission: SAX J1324.5-6313, SAX J1752.3-3128, SAX J1752.3-3128I, SAX J1324.5-6313V, and SAX J1818.7+1424. We designate candidate persistent sources for four X-ray bursters. All candidates are detected at a persistent luminosity level of 1032-33 erg s-1

In an ongoing effort to study the formation and evolution of galactic bulges, we have investigated the position of 19 bulges of type S0-Sbc on the Fundamental Plane (FP). We find that bulges, in both B and K band, lie close to but slightly below the FP defined by ellipticals and S0s, i.e. are slightly brighter. There are hints that bulges of later
