Probing initial distributions of orbital eccentricity and disc misalignment via polar discs / S. Ceppi, N. Cuello, G. Lodato, C. Longarini, D.J. Price, D. Elsender, M.R. Bate. - In: ASTRONOMY & ASTROPHYSICS. - ISSN 0004-6361. - 682:(2024), pp. A104.1-A104.7. [10.1051/0004-6361/202348375]
Abstract:
In a population of multiple protostellar systems with discs, the sub-population of circumbinary discs whose orbital plane is highly misaligned with respect to the binary's orbital plane constrains the initial distribution of orbital parameters of the whole population. We show that by measuring the polar disc fraction and the average orbital eccentricity in the polar discs, one can constrain the distributions of initial eccentricity and mutual inclination in multiple stellar systems at birth.
