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

Proxima Centauri, the nearest star to the sun, hosts a habitable-zone planet (Anglada-Escude' et al. 2016 Nature 536, 437). Several teams have sought Proxima b's transits using ground-based photometry, and have reported tentative transit detections (Liu et al. 2018 AJ 155, 12; Blank et al. 2018 AJ 155, 228; others). Proxima, a modest-sized M-dwarf

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).

We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multicomponent photometric decomposition based on Sloan Digital Sky Survey imaging to Calar Alto Legacy Integral Field Area Integral Field Spectroscopy (IFS) datacubes for a
