A search for interstellar bubbles surrounding massive stars in Perseus OB1

We have examined the interstellar medium in the vicinity of massive stars belonging to the Per OB1 association based on neutral hydrogen 21 cm observations obtained with the 100 m radio telescope at Effelsberg (HPBW = 8′.4) and complementary data from the Leiden-Dwingeloo H I Survey (HPBW = 36′).

This large H I shell has an infrared counterpart.Facultad de Ciencias Astronómicas y GeofísicasInstituto Argentino de Radioastronomía2000info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf1963-1973http://sedici.unlp.edu.ar/handle/10915/83551enginfo:eu-repo/semantics/altIdentifier/issn/0004-6256info:eu-repo/semantics/altIdentifier/doi/10.1086/301556info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/4.0/Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:53:54Zoai:sedici.unlp.edu.ar:10915/83551Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:53:55.149SEDICI (UNLP) - Universidad Nacional de La Platafalse
