Deficit luminoso per l'Acquario

Il sistema binario della famiglia dei polari intermedi fa registrare un comportamento anomalo: stop ai rifornimenti di gas dalla prima stella alla nana bianca sua compagna e "trend" di luce negativo
“Rifornimenti” interrotti nel cielo dell’Acquario.

C’era una volta una strana coppia stellare chiusa in un sistema binario, composta da una nana bianca e da una compagna "generosa", che inviava gas alla prima nutrendola e agevolandone i processi di accrescimento. I due soggetti dello studio, condotto dai ricercatori dell’Università di Notre Dame, sono due astri che abitano nella nostra galassia a 500 anni luce dalla Terra, in corrispondenza della costellazione dell’Acquario: racchiuse in un sistema binario di tipo polare intermedio noto come FO Aquarii, le due stelle hanno fatto registrare un comportamento anomalo.

Galaxy Murder Mystery

 

 

It’s the big astrophysical whodunnit. Across the Universe, galaxies are being killed and the question scientists want answered is, what’s killing them?

New research published today by a global team of researchers, based at the International Centre for Radio Astronomy Research (ICRAR), seeks to answer that question. The study reveals that a phenomenon called ram-pressure stripping is more prevalent than previously thought, driving gas from galaxies and sending them to an early death by depriving them of the material to make new stars.
