For stars of intermediate mass
, like Elias 1, it is rather uncommon to have a strong X-ray emission, let alone an X-ray flare.
This is the best detection to date of such long sought after intermediate mass
Either a stellar mass black hole was accreting at extreme rates or there was a new subspecies of intermediate mass
black holes accreting at lower rates.
The existence of a star cluster around the black hole in turn gives clues about where the intermediate mass
black hole may have come from, and why it lies in its present location in ESO 243-49.
If confirmed, this discovery would be a cosmic double play, as it would be strong evidence for an intermediate mass
black hole, which has been a hotly debated topic, and would mark the first time such a black hole has been caught tearing a star apart.
Stars of intermediate mass
(1-8 solar masses) terminate their life as an Earth-sized white dwarf after the exhaustion of their nuclear fuel.
Are there intermediate mass
black holes in the Galactic center?
The birth of planetary nebulae, resulting from the death of low and intermediate mass
stars, is usually thought of as a slow process, in contrast with the intense supernovae that massive stars produce.
This new work, led by Grzegorz Pietrzynski of the Universidad de Concepcion in Chile and Warsaw University Observatory in Poland, used 16-years-worth of observations to identify a sample of intermediate mass
binary stars with extremely long orbital periods, perfect for measuring precise and accurate distances.
Abstract: Low and intermediate mass
stars have initial masses less than about 8 MSUN.
It could be an exotic object such as a pulsar, mini-quasar, supernova remnant or an intermediate mass
