cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryproper-motionsDeep and wide-field optical photometric observations along with multiwavelength archival data sets have been employed to study the physical properties of the cluster NGC 6910. The study also examines the impact of massive stars on their environment. The age, distance, and reddening of the cluster are estimated to be ~4.5Myr, 1.72+/-0.08kpc, and E(B-V)_min_=0.95mag, respectively. The mass function slope ({Gamma}=-0.74+/-0.15) in the cluster region is found to be flatter than the Salpeter value (-1.35), indicating the presence of an excess number of massive stars. The cluster also shows mass segregation toward the central region due to their formation processes. The distribution of warm dust emission is investigated toward the central region of the cluster, showing the signature of the impact of massive stars within the cluster region. Radio continuum clumps powered by massive B-type stars (age range ~0.07-0.12Myr) are traced that are located away from the center of the stellar cluster NGC 6910 (age ~4.5Myr). Based on the values of different pressure components exerted by massive stars, the photoionized gas associated with the cluster is found to be the dominant feedback mechanism in the cluster. Overall, the massive stars in the cluster might have triggered the birth of young, massive B-type stars in the cluster. This argument is supported with evidence of the observed age gradient between the cluster and the powering sources of the radio clumps.2020ApJ...896...29Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/896/29CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)I/345 : Gaia DR2 (Gaia Collaboration, 2018)VI/128 : Log of CGPS exposures (Taylor+, 2003-)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/AJ/101/1408 : Massive stars in Cyg OB2.
