Spicules of the so-called type II were suggested to be relevant for coronal heating because of their ubiquity on the solar surface and their eventual extension into the corona. We investigate whether solar spicules are heated to transition-region or coronal temperatures and reach coronal heights ({≫} 6 Mm) using multiwavelength observations of limb

We present optical and near-infrared spectroscopy (600-1000 nm) of eight faint (I > 18) very red (R - I > 2.2) objects discovered in a recent deep CCD survey of the Pleiades cluster by ZapateroOsorio, Rebolo, & Martin. We compare them with reliable cluster members like PP1 15 and Teide 1, and with several field very late type dwarfs (M4-M9.5)

We have started a near-infrared spectroscopic study of the Veritas asteroid family. This family is of particular interest for several reasons: 1) This 8.2 million-year-old family contains fresh fragments of a primitive parent body (Nesvorney et al., 2005). 2) Interplanetary dust from the Veritas collision makes up over 25% of interplanetary dust

The measurements reported were made during a flight to an altitude of 40 km, on Mar. 13, 1974. A polarizing Michelson interferometer cooled, by a liquid helium bath, to a temperature of 1.4 K was used in the measurements. One hour of useful time was achieved at float altitude. The fitted spectrum obtained is shown in a graph. The measured spectrum

The ring images presented here are part of a larger William Herschel Telescope (WHT) imaging survey (1999 and 2000) conducted to characterize the nuclear and circumnuclear morphology in nearby galaxies (Paper I, Knapen et al., 2006A&A...448..489K). (2 data files).
