The group of astronomers from the Canadian university of Calgary assumes that discovered in September, 2006 the brightest supernew 2006gy can be quarko-star.
Supernew 2006gy is removed from the Earth on 238 million light years. Experts inform, that this one is the brightest supernew of ever found stars - energy of its radiation surpasses an average energy of radiation of a supernew star at about two units.
Therefore Calgary experts Denis Likhi and Rashyd Wade put forward some hypotheses, explaining its brightness. Scientists have assumed that brightness says abut a birth of so-called quarko-star consisting of free quarks.
Quarks are the hypothetical particles which do not exist in the nature separately. They can be met only in groups of two (forming quickly disintegrating mesons) or of three (forming protons and neutrons). Physics assume that when the substance is compressed up to ultrahigh density, protons and neutrons disintegrate to separate quarks, forming thus a strange substance. The cubic centimeter of such substance would weigh about billion tons.
