SuperWASP observations of the 2007 outburst of Comet 17P/Holmes
We present wide-field imaging of the 2007 outburst of Comet 17P/Holmes obtained serendipitously by SuperWASP-North on 17 nights over a 42-night period beginning on the night (2007 October 22–23) immediately prior to the outburst. Photometry of 17P’s unresolved coma in SuperWASP data taken on the first night of the outburst is consistent with exponential brightening, suggesting that the rapid in...
متن کاملPeculiar Near-Nucleus Outgassing of Comet 17P/Holmes During Its 2007 Outburst
We present high angular resolution Submillimeter Array observations of the outbursting Jupiter family comet 17P/Holmes on 2007 October 26–29, achieving a spatial resolution of 2.5, or∼3000 km at the comet distance. The observations resulted in detections of the rotational lines CO 3–2, HCN 4–3, HCN 4–3, CS 7–6, H2CO 31,2-21,1, H2S 22,0–21,1, and multiple CH3OH lines, along with the associated d...
متن کاملLarge Excess of Heavy Nitrogen in Both Hydrogen Cyanide and Cyanogen from Comet 17p/holmes
From millimeter and optical observations of the Jupiter-family comet 17P/Holmes performed soon after its huge outburst of October 24, 2007, we derive 14N/15N=139±26 in HCN, and 14N/15N=165±40 in CN, establishing that HCN has the same non-terrestrial isotopic composition as CN. The same conclusion is obtained for the long-period comet C/1995 O1 (Hale-Bopp) after a reanalysis of previously publis...
متن کاملHolmes
The European Research Council has recently funded HOLMES, a new experiment to directly measure the neutrino mass. HOLMES will perform a calorimetric measurement of the energy released in the decay of 163Ho. The calorimetric measurement eliminates systematic uncertainties arising from the use of external beta sources, as in experiments with beta spectrometers. This measurement was proposed in 19...
متن کاملAsynchronous Online Discussion - Holmes
The online learning environment provides the opportunity for remote groups of students to interact with instructors and each other. Most web based learning platforms facilitate asynchronous online discussions between participants. These discussion forums are designed to replicate the face to face tutorial setting and provide a medium for the expression and development of student ideas. In this ...
