Neutron Star Binaries in Open Clusters [PDF]
International Astronomical Union Colloquium, 1996 We use N-body simulations of open clusters to examine the evolutionary history of binaries containing neutron stars. The model includes consistent treatment of all the relevant processes (Aarseth 1996): • Synthetic stellar evolution – mass and radius as a function of time (Eggleton et al.

Membership Analysis and 3D Kinematics of the Star-forming Complex around Trumpler 37 Using Gaia-DR3
The Astrophysical Journal, 2023 Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are very useful for studying large star-forming complexes.

Dynamics of Open Star Clusters [PDF]
Symposium - International Astronomical Union, 1985 The dynamical evolution of open star clusters has been studied successfully by numerical N-body simulations. We compare in detail the theoretically predicted lifetimes with those derived from the observed age distribution of open clusters. Rare but efficient encounters between clusters and giant molecular clouds are probably responsible for the sudden ...

Non-stationarity of Open Star Clusters [PDF]
, 2021 The monograph poses issues related to the study of the non-stationarity of open star clusters (OSCs), starting with an analysis of the properties of the trajectories of individual stars to the study of collective motion of stars. A discussion of the dynamics of correlations and wave processes in such clusters is presented. The mechanisms of the dynamic

Stars with Abnormal Spectra in Open Clusters [PDF]
Symposium - International Astronomical Union, 1980 From the literature a list of stars with abnormal spectra belonging to open clusters was compiled. This list is included in Lyngå's catalogue of open clusters. With this data it becomes possible to derive a correlation with the age, compiled by W. Buscombe and which appears also in Lyngå's catalogue.

Cool Carbon Stars in Open Clusters [PDF]
Symposium - International Astronomical Union, 1975 By combining lists of carbon stars with the catalogue of open clusters (Alter et al., 1970), a list of variable carbon stars, being probable members of clusters is given. The number of stars is too small to derive reliable statistics on cluster membership. Too few radial velocities are yet available.

A uvbyCaHβ CCD Analysis of the Open Cluster Standard, M67, and Its Relation to NGC 752
The Astronomical Journal, 2023 Precision CCD uvbyCa H β photometry is presented of the old cluster, M67, covering one square degree with typical internal precision at the 0.005–0.020 mag level to V ∼ 17.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Chemotherapy‐induced peripheral neuropathy remains a major complication in pediatric cancer, with disrupted somatosensory and nociceptive processing being a key aspect. This review synthesizes empirical studies on alterations in somatosensory and nociceptive processing in children and adolescents with cancer.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
