The membership of stars, density profile and mass segregation in open clusters using a new machine learning-based method
Mohammad Noormohammadi, Mehdi Khakian Ghomi, Hossein Haghi
A combination of two unsupervised machine learning algorithms, DBSCAN and GMM are used to find members with a high probability of twelve open clusters, M38, NGC2099, Coma Ber, NGC7…
The family pictures of our neighbours: investigating the mass function and dynamical parameters of nearby open clusters
H. Ebrahimi, A. Sollima, H. Haghi
We determine the mass functions (MFs) and the dynamical parameters of 15 nearby open clusters (OCs) using the unprecedented data set of the Gaia Early Data Release 3. We select the…
Second generation star formation in globular clusters of different masses
A. Yaghoobi, F. Calura, J. Rosdahl +1
By means of three-dimensional hydrodynamical simulations, we investigate the formation of second generation (SG) stars in young globular clusters of different masses. We consider c…
Direct N-body simulations of globular clusters -- III. Palomar\,4 on an eccentric orbit
Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa +2
Palomar 4 is a low-density globular cluster with a current mass in the outer halo of the Milky Way with a two-body relaxation time of the order of a Hubble…
Testing modified gravity with dwarf spheroidal galaxies
Hosein Haghi, Vahid Amiri
The observed velocity dispersion of the classical dwarf spheroidal (dSph) galaxies of the Milky Way (MW) requires the Newtonian stellar mass-to-light () ratios in the range…
The effect of primordial mass segregation on the size scale of globular clusters
Hosein Haghi, Seyed Mohammad Hoseini-Rad, Akram Hasani Zonoozi +1
We use direct -body calculations to investigate the impact of primordial mass segregation on the size scale and mass-loss rate of star clusters in a galactic tidal field. We run…
