Open clusters identifying by multi-scale density feature learning
Wang, Min; Shao, Zhengyi; Xiang, Yaobing +2 more
Open clusters (OCs) are important objects in exploring the structure and history of the Milky Way. Large amount of sky survey data can be used to detect OCs. However, analyzing these data manually has become a bottleneck of OC identification. This study proposes a multi-scale density feature learning (MSDFL), which includes the open cluster kernel…
GALEX photometry of the open cluster NGC 752
Smith, Graeme H.
Ultraviolet photometry from the GALEX mission is compiled for a sample of main sequence stars and red giants in the open cluster NGC 752. This is one of the few ensembles of coveal near-solar abundance FGK stars for which near-ultraviolet and far-ultraviolet magnitudes are available from GALEX. Cluster members are identified on the basis of Gaia p…
On properties of coronal mass ejection-solar flare linked events
Youssef, M.
In the present paper, the relation between the CMEs and their linked solar flares is examined during the entire solar cycle 23. During this solar cycle and under certain temporal and spatial conditions, 521 CMEs linked with solar flares are selected. These selected CMEs are separated into two groups according to their time of detection, 254 Before…
