Deriving physical parameters of unresolved star clusters. IX. Sky background effects in the aperture photometry
Karolis Daugevičius, Rima Stonkutė, Eimantas Kriščiūnas +2
The aperture photometry method is a powerful tool that enables us to study large star cluster systems efficiently. However, its accuracy depends on various factors, including the s…
Deriving physical parameters of unresolved star clusters. VIII. Limits of aperture photometry for star cluster studies
Karolis Daugevičius, Eimantas Kriščiūnas, Erikas Cicėnas +2
Recently, it has been noticed that the discrepancies in the integrated colour indices (CIs) between star clusters and models are mostly due to the projection of bright stars in the…
Deriving star cluster parameters with convolutional neural networks. I. Age, mass, and size
J. Bialopetravičius, D. Narbutis, V. Vansevičius
Context. Convolutional neural networks (CNNs) have been proven to perform fast classification and detection on natural images and have potential to infer astrophysical parameters o…
Deriving physical parameters of unresolved star clusters III. Application to M31 PHAT clusters
Philippe de Meulenaer, Donatas Narbutis, Tadas Mineikis +1
This study is the third of a series that investigates the degeneracy and stochasticity problems present in the determination of physical parameters such as age, mass, extinction, a…
Stochasticity effects on derivation of physical parameters of unresolved star clusters
Philippe de Meulenaer, Donatas Narbutis, Tadas Mineikis +1
We developed a method for a fast modeling of broad-band UBVRI integrated magnitudes of unresolved star clusters and used it to derive their physical parameters (age, mass, and exti…
Deriving physical parameters of unresolved star clusters. I. Age, mass, and extinction degeneracies
Philippe de Meulenaer, Donatas Narbutis, Tadas Mineikis +1
Context. Stochasticity and physical parameter degeneracy problems complicate the derivation of the parameters (age, mass, and extinction) of unresolved star clusters when using bro…
