... Mars to Appear Normal this August . ... October is the best month to see Mars this year. ... As Earth catches up to Mars in their respective orbits around the Sun, Mars will keep rising earlier in the night. On 2005 October 30, Earth will have caught up to Mars and the planets will be the nearest to each other in their orbits -- this time around. On October 30, Mars will be nearly opposite to the Sun, rise at sunset, set at sunrise, and appear highest and brightest around midnight. ...

... The first step to improve the FORS calibration is therefore to obtain data to allow a computation of the illumination correction across the field. ... Another limitation on the calibration accuracy has been the brightness of the Landolt standards which have forced the use of extremely short exposures introducing small but non-negligible shutter-time errors and also resulting in a very small number of useful standards per frame. ...

Figure out the behaviour of each parcel of gas, and then add them all up to find the light curve. 5.4 (3pts) Using expression from problem 5.2, derive the expression for the time after SN explosion date, when the first light from the ionised ring reaches Earth. Using the expression from problem 5.2, derive the expression for the time after SN explosion date when the maximum brightness of the ring occurs. ...

... A simple Virasoro vertex algebra is rational (and -2 semisimple as well) iff its central charge is of the form c = 1 - 6(pppp ) , where p, p are relatively prime integers, greater than 1 (which are central charges of the so called minimal models). A simple affine vertex algebra Vk (g), attached to a simple Lie algebra g is rational (and semisimple as well) iff its level k is a non-negative integer. ... We call such f an exceptional nilpotent and such k an exceptional level. ...
