T PYXIDIS Meaning and
Definition
-
T Pyxidis is a term that refers to a star system located within the constellation Pyxis. The star system consists of a binary star, which means it is composed of two stars that orbit around a common center of mass. The primary star in the system is a white dwarf, which is a highly dense and hot remnant of a star that has exhausted its nuclear fuel. It is believed that this white dwarf was once a massive star that underwent a supernova explosion, resulting in the ejection of its outer layers and leaving behind the dense core.
The companion star in the T Pyxidis system is classified as a subgiant star, which is a relatively large and bright star in the late stages of its evolution. This companion star is the source of a stream of gas that accretes onto the white dwarf. As this gas accumulates on the surface of the white dwarf, a critical mass is reached, triggering a thermonuclear explosion known as a nova event. These nova events in the T Pyxidis system occur periodically, with the system undergoing recurrent nova outbursts, increasing its brightness significantly for a brief duration.
The study of T Pyxidis and similar star systems can provide valuable insights into stellar evolution, binary interactions, and the mechanisms driving nova events. Astronomers use telescopes and other observational tools to observe and study the behavior and characteristics of T Pyxidis, aiming to unravel the mysteries surrounding the dynamics of binary star systems and the triggers of recurrent nova explosions.
Etymology of T PYXIDIS
The word "pyxidis" has its origin in Greek. It is derived from the Greek word "pyxis" (πυξίς), which originally referred to a small box or container. In this case, the "t" before "pyxidis" is actually the article "το" (to) in Greek, meaning "the". Therefore, "t pyxidis" translates to "the pyxis" in English.
