Biography
Juan Carlos Muzzio Passanante, Argentine astronomer (Buenos Aires 19 January 1946 –
From Italian and Spanish descent
Discovered hundreds of objects and H-alpha emitting stars
Discovered asteroids 3666 Holman and 7372 Emimar (in honor to his daughters) in 1972
Predicted the existence of galaxy satellites of masses intermediate between galaxies and globular clusters
Discovered and named globular cluster swapping
With J.C. Forte & R.E. Martínez. On the origin of the globular cluster system of M87. Astron. J. 87(11):1465, 1982
Discovered that dwarf stars are totally destroyed, but the core survives and becomes like a globular cluster of giant stars
With L.P. Bassino & L.P. Rabolli. Are globular clusters the nuclei of cannibalized dwarf galaxies? Astrophys. J. 431:634-9, 1994
Showed the role of chaos in elliptic galaxies (2000)
Chaos in elliptic galaxies (2001)
Showed that chaotic stellar motion occurs in galactic satellites
With D.D. Carpintero, M.M. Vergne & F.C. Wachlin. Chaotic orbits in galactic satellites. Celest. Mech. Dynam, Astron. 85(3):247-67, 2003
Showed the existence of partially chaotic orbits
Partially chaotic orbits in a perturbed cubic force model. Monthly Not. Roy. Astron. Soc. 471(4):4099-10, 2017
