Low-frequency GMRT observations of the magnetic Bp star HR Lup (HD 133880)

We present radio observations of the magnetic chemically peculiar Bp star HR Lup (HD 133880) at 647 and 277 MHz with the GMRT. At both frequencies the source is not detected but we are able to determine upper limits to the emission. The 647 MHz limits are particularly useful, with a 5\sigma\ value of 0.45 mJy. Also, no large enhancements of the emission were seen. The non-detections, along with previously published higher frequency detections, provide evidence that an optically thick gyrosynchrotron model is the correct mechanism for the radio emission of HR Lup.Comment: 7 pages, accepted for publication in the Bulletin of the Astronomical Society of India, to appear in the June issu

Persisting mobile phone use while driving and possible solutions for New Zealand

In New Zealand the use of hand-held phones while driving was prohibited in 2009, but ‘hands-free’ phones are still permitted. We recently presented the results of an observational study into mobile phone among Wellington drivers at a conference (for details see the proceedings). The main findings were that out of 8335 cars systematically observed at traffic lights and 9520 cars in moving traffic (each at three different Wellington locations), the use of mobile phones was 1.87% (95%CI: 1.60-2.18) and 1.34% (95%CI: 1.13-1.59) respectively

Boxwoods

True boxwood, commonly called Turkish boxwood, is derived from a small group of plants, of which the common evergreen ·box of our gardens is the type. To this group the famous botanist Linnaeus gave the generic name of Buxis, the Latin for box tree. He called the best known member of it Buxis sempervirens, which is\u27 but another form of Ovid\u27s buxus perpetuo virens, the evergreen box. For long this was considered the only species, though various forms and varieties came to be recognized, several of which have since been elevated by other botanists to specific rank

Cocobolo

Cocobolo is a valuable timber of commerce that has been in use in this country, particularly for handles of cutlery, for more than fifty years. It is produced by certain species of Dalbergia indigenous to Central America and southwestern Mexico. The present commercial sources are Panama, Costa Rica, and Nicaragua

Extrasolar Planets in the Classroom

The field of extrasolar planets is still, in comparison with other astrophysical topics, in its infancy. There have been about 300 or so extrasolar planets detected and their detection has been accomplished by various different techniques. Here we present a simple laboratory experiment to show how planets are detected using the transit technique. Following the simple analysis procedure describe we are able to determine the planetary radius to be 1.27 +/- 0.20 R_{J} which, within errors agrees with the establish value of 1.32 +/- 0.25 R_{J}.Comment: 7 pages, 2 figures, published in Physics Educatio
