Spectroscopic and Photometric Observations of SN IIn 1995N
A. Pastorello, I. Aretxaga, L. Zampieri +2
We present the results of a long-term program of monitoring of the famous SN 1995N, observed both in photometry (UBVRIJHK bands) and optical spectroscopy. The observations span a p…
Supernova search at intermediate z. I. Spectroscopic analysis
G. Altavilla, P. Ruiz-Lapuente, A. Balastegui +7
We study 8 supernovae discovered as part of the International Time Programme (ITP) project ``Omega and Lambda from Supernovae and the Physics of Supernova Explosions'' at the Europ…
Type Ia SN1999cw: photometric and spectroscopic study
F. Bufano, M. Turatto, S. Benetti +4
The preliminary analysis of the optical data of SN1999cw show that this object has the photometric and spectroscopic behavior of a Type Ia supernova similar to SN1991T, reaching an…
The tetra-lobed planetary nebula NGC 1501
Franco Sabbadin, Stefano Benetti, Enrico Cappellaro +1
Direct imagery and long-slit, spatially resolved echellograms of the high excitation planetary nebula NGC 1501 allowed us to study in detail the expansion velocity field, the physi…
Near-infrared detection and optical follow-up of the GRB990705 afterglow
N. Masetti
Optical and near-infrared observations of the GRB990705 error box were carried out with ESO telescopes at La Silla and Paranal in Chile and with the NOAO SPIREX 0.6-meter telescope…
Tomography of the low excitation planetary nebula NGC 40
F. Sabbadin, E. Cappellaro, S. Benetti +2
Spatially resolved, long-slit echellograms at different position angles of the bright, low excitation planetary nebula NGC 40 indicate that, the higher is the gas excitation, the f…
