The Universality of the Companion Mass Ratio Distribution
Maddalena Reggiani, Michael R. Meyer
We present new results regarding the companion mass-ratio distribution (CMRD) of stars, as a follow-up of our previous work. We used a maximum-likelihood-estimation method to re-de…
The binary companion mass ratio distribution: an imprint of the star formation process?
Richard J. Parker, Maddalena M. Reggiani
We explore the effects of dynamical evolution in dense clusters on the companion mass ratio distribution (CMRD) of binary stars. Binary systems are destroyed by interactions with o…
Direct imaging constraints on planet populations detected by microlensing
Sascha P. Quanz, David Lafreniere, Michael R. Meyer +2
Results from gravitational microlensing suggested the existence of a large population of free-floating planetary mass objects. The main conclusion from this work was partly based o…
Quantitative Evidence for an Intrinsic Age Spread in the Orion Nebula Cluster
M. Reggiani, M. Robberto, N. Da Rio +3
Aims. We present a study of the distribution of stellar ages in the Orion Nebula Cluster (ONC) based on accurate HST photometry taken from the HST Treasury Program observations of…
Binary Formation Mechanisms: Constraints from the Companion Mass Ratio Distribution
Maddalena M. Reggiani, Michael R. Meyer
We present a statistical comparison of the mass ratio distribution of companions, as observed in different multiplicity surveys, to the most recent estimate of the single object ma…
