We present photometric and spectroscopic data of the Type II-P supernova (SN II-P) 2003gd, which was discovered in M74 close to the end of its plateau phase. SN...
Indene was polymerized to polyindene (PI) through a cationic mechanism using TiCl4•2THF complex as initiator. The cationic mechanism was investigated through...
A Study on the Synthesis and Stability of the C60 Fullerene/Tetracene Adduct
A C60 fullerene/tetracene adduct was synthesized and studied by electronic absorption spectroscopy and FT-IR spectroscopy. Essentially the mono-adduct was...
A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
Context. Transiting sub-Neptune-type planets, with radii approximately between 2 and 4 R ⊕, are of particular interest as their study allows us to gain insight...
A sub-Neptune transiting the young field star HD 18599 at 40 pc
Transiting exoplanets orbiting young nearby stars are ideal laboratories for testing theories of planet formation and evolution. However, to date only a handful...
A Subarcsecond Resolution Near-Infrared Study of Seyfert and ``Normal'' Galaxies. II. Morphology
We present a detailed study of the bar fraction in the CfA sample of Seyfert galaxies and in a carefully selected control sample of nonactive galaxies to...
A Subarcsecond-Resolution Near-Infrared Study of Seyfert and ``Normal'' Galaxies. I. Imaging Data
We present new high-resolution near-infrared observations in the J, H, and K bands, obtained to study the properties of Seyfert host galaxies. The data set...
A substantial amount of hidden magnetic energy in the quiet Sun
Deciphering and understanding the small-scale magnetic activity of the quiet solar photosphere should help to solve many of the key problems of solar and...
A Substantial Population of Red Galaxies at z > 2: Modeling of the Spectral Energy Distributions of an Extended Sample
We investigate the nature of the substantial population of high-redshift galaxies with Js-Ks>=2.3 colors recently discovered as part of our Faint Infrared...
