We present the discovery of the common proper motion M9 + L0 binary DENIS J220002.05−303832.9AB, identified serendipitously with the SpeX near infrared imager/spectrograph. Spectral types are derived from resolved near infrared spectroscopy of the wellseparated (1. 09±0. 06) components and comparison to equivalent data for M and L dwarf spectral standards. Physical association is deduced from t...

We report deep 3.6 cm radio observations of six very rapidly rotating late-type dwarf stars in the Pleiades open cluster, distributed in spectral class from F9 to M0. This study, supplemented by our previous radio detections of three G8-K2 dwarfs in the Pleiades (Lim & White 1995; hereinafter LW95), completes our small census of Pleiades ultrafast rotators with spectral types spanning the range...

Evidence is presented that 2MASS J03202839−0446358, a late-type dwarf with discrepant optical (M8:) and near-infrared (L1) spectral types, is an as-yet unresolved stellar/brown dwarf binary with late-type M dwarf and T dwarf components. This conclusion is based on low-resolution, near-infrared spectroscopy that reveals a subtle but distinctive absorption feature at 1.6 μm. The feature, which is...

'Dwarf stature' maize variety offers promises to withstand unfavorable growth environments of Kharif season. But, for developing such variety, dwarf stature inbred lines must be available. Here, twenty-four F3 populations of white maize were evaluated though assessment of their genetic variability, heritability, and character association for selection of dwarf stature promising lines based on y...

There exists an inherent difficulty in the original algorithm for the construction of Dwarf, which prevents it from constructing true Dwarfs. We explained when and why it introduces suffix redundancies into the Dwarf structure. To solve this problem, we proposed a completely new algorithm called PID. It bottom-up computes partitions of a fact table, and inserts them into the Dwarf structure. If...

Optical observations of the GRB970508 optical remnant were continued with the 6-m telescope of SAO RAS in standard the BV RcIc bands in Oct.-Dec. 1997 and in Jan. 1998. The results of photometry of the GRB970508 remnant and of three nearby galaxies are presented. The BV RcIc light curves of the GRB970508 remnant can be described by a power law plus a constant F (t) = F0(t− t0) + C. In determina...
