An exotic star is a compact star composed of something other than electrons, protons, and neutrons balanced against gravitational collapse by degeneracy pressure or other quantum properties. These include quark and strange stars (composed of quark or strange matter) and the more speculative preon stars (composed of preons).

Exotic stars are largely theoretical, but observations released by the Chandra X-Ray Observatory on April 10, 2002 detected two candidate quark stars, designated RX J1856.5-3754 and 3C58, which had previously been thought to be neutron stars. Based on the known laws of physics, the former appeared much smaller and the latter much colder than they should, suggesting that they are composed of material denser than neutronium. However, these observations are met with skepticism by researchers who say the results were not conclusive.^[who?]

It is possible that the neutrons will decompose into their component up and down quarks when sufficient gravitational pressure is applied. In this case, the star will shrink further and become denser, but it may survive in this new state indefinitely if no extra mass is added. It has become a very large nucleon. A star in this hypothetical state is called a quark star. If quark stars contain strange matter, then they are called strange stars. The pulsars RX J1856.5-3754 and 3C58 have been suggested as possible quark stars.

Priyanka Chopra (pronounced [prɪˈjəŋkaː ˈtʃoːpɽaː]; born 18 July 1982) is an Indian actress, singer-songwriter and former Miss World. Before starting her acting career, she worked as a model and gained fame after winning the Miss World title in 2000. She is often referred to by the nickname "Piggy Chops", which was given to her by co-stars on the set of the film Bluffmaster! During her career, Chopra has received four Filmfare Awards, among seven nominations and one National Film Award for Best Actress.

Chopra made her acting debut with the 2002 Tamil film Thamizhan. The following year, she made her Bollywood film debut with The Hero: Love Story of a Spy and followed it with the hit Andaaz, for which she won a Filmfare Best Female Debut Award. In 2004, she became the second woman to win the Filmfare Best Villain Award, which she received for her critically acclaimed performance in Aitraaz. She subsequently appeared in successful films like Mujhse Shaadi Karogi (2004), Waqt: The Race Against Time (2005), Krrish (2006) and Don (2006).
