Received 2015 October 22; in original form 2015 August 9 ABSTRACT In recent years, several small basaltic V-type asteroids have been identified all around the main belt. Most of them are members of the Vesta dynamical family, but an increasingly large number appear to have no link with it. The question that arises is whether all these basaltic objects do indeed come from Vesta. -

Three of these objects are spectrally distinct from all classifications in the Bus-DeMeo system and could represent spectral end members in the existing taxonomy or be representatives of a new spectral type. The remainder of the sample are classified as V- or R- type. All of these asteroids are dynamically detached from the Vesta collisional family, but are too small to be intact differentiated parent bodies, implying that they originated from differentiated planetesimals which have since been destroyed or ejected from the solar system. -

LIGHTCURVE ANALYSIS FOR 4167 RIEMANN Amy Zhao, Ashok Aggarwal, and Caroline Odden Phillips Academy Observatory (I12) 180 Main Street Andover, MA 01810 USA [email protected] (Received: 10 June) Photometric observations of 4167 Riemann were made over six nights in 2014 April. A synodic period of P = 4.060 ± 0.001 hours was derived from the data. 4167 Riemann is a main-belt asteroid discovered in 1978 by L. V. Period analysis was carried out by the authors using MPO Canopus Zhuraveya. Observations of the asteroid were conducted at the and its Fourier analysis feature developed by Harris (Harris et al., Phillips Academy Observatory, which is equipped with a 0.4-m f/8 1989). The resulting lightcurve consists of 288 data points. The reflecting telescope by DFM Engineering. Images were taken with period spectrum strongly favors the bimodal solution. The an SBIG 1301-E CCD camera that has a 1280x1024 array of 16- resulting lightcurve has synodic period P = 4.060 ± 0.001 hours micron pixels. The resulting image scale was 1.0 arcsecond per and amplitude 0.17 mag. Dips in the period spectrum were also pixel. Exposures were 300 seconds and taken primarily at –35°C. noted at 8.1200 hours (2P) and at 6.0984 hours (3/2P). A search of All images were guided, unbinned, and unfiltered. Images were the Asteroid Lightcurve Database (Warner et al., 2009) and other dark and flat-field corrected with Maxim DL. -

The CR chondrites are of microns due to the presence of pyroxene. Some of these meteorite types have special significance in this regard, because they contain the most primitive spectra that are quite similar, but nevertheless have characteristics (e.g., carbonaceous material currently known [3]. -
