Red dwarf star

Red dwarf star. Artwork representing the intense activity of a red dwarf star. These are among the least massive stars in the universe ranging from 0.1 to 0.7 solar masses. The star shown here belongs to a subclass of red dwarf stars, known as the flare stars, which are characterised by frequent (3-4 per hour) flares. These are seen as sudden brightenings with a typical rising time between 1s and 1min and a slower fading time between 1min and 1 hour. During a flare, filaments of gas in the atmosphere are accelerated outwards with speeds up to 1000km/s. Such speeds are greater than the escape velocity and therefore the matter ejected will be lost from the parent star

E. Rutherford and his wife at Trinity College

The New Zealand born physicist Sir Ernest Rutherford (1871-1937) and his wife Mary Newton at Trinity College in Cambridge (1921). He identified three types of radiations produced by radioactive decay which he called alpha, beta and gamma rays. He later proved that alpha rays were helium nuclei. In 1911 he elaborated a model in which the positive charge of the atom (protons) was concentrated in a very small region, the nucleus. He also showed that the structure of an atom could be changed (nuclear transmutation) by bombarding it with alpha particles. He is considered to be the father of nuclear physics and in 1908 he was awarded the Nobel Prize for chemistry
