The young stars are often sources prodigious x-ray observations with the satellite XMM-Newton of the European Space Agency show that RZ Piscium. Its total emission of X-rays is approximately 1,000 times that of our Sun.
Observations based on earth show that the temperature of the surface of the star is around 5.330 degrees Celsius, just a little cooler than the Sun. We also show that RZ Piscium is enriched with the indicator element lithium, which is destroyed slowly by the nuclear reactions inside stars and serves as a clock that indicates the time elapsed from the birth of a star.
The telescopes based on earth also reveal large amounts of dust and hydrogen-rich gas in the system, suggesting that large patches of this material are in orbit around the star and cause falls of brightness.
Kristina Punzi, phd student at the Rochester Institute of Technology (RIT) in New York and lead author of an article published in The Astronomical Journal that discusses new findings on this star, stated in a press release from the Center NASA Goddard: “Although there could be other explanations, we suggest that this material could have been produced by the decomposition of bodies in orbit mass close to the star”.
It is possible that the tides of the star might be drawing material from a companion substelar close, or a giant planet, producing currents of intermittent gas and dust, or that the partner is already completely dissolved. Another possibility is that one or more massive planets and rich in gas on the system suffered a catastrophic collision in the past, astronomically recent.
