The Young Stellar Population of IC 1613 I . A New Catalogue of OB Associations ⋆ ⋆ ⋆
Context. Determining the parameters of massive stars is crucial to understand many processes in galaxies and the Universe, since these objects are important sources of ionization, chemical enrichment and momentum. 10m class telescopes enable us to perform detailed quantitative spectroscopic analyses of massive stars in other galaxies, sampling areas of different metallicity. Relating the stars ...
متن کاملThe First Known Mira - type Variable Star in IC 1613
King, Modjaz, & Li (1999) discovered Nova 1999 in IC 1613 at Lick Observatory. Both Fugazza et al. (2000) and Borissova et al. (2000) questioned this classification, because they were able to detect the star on images obtained in previous years. In infrared frames taken on Oct. 15, 1998, the Nova 1999 has (J −K) = 1.14 and K = 14.69 mag. Our light curve study, based primarily on 92 unfiltered L...
متن کاملVlt Spectroscopy of Blue Supergiants in Ic 1613 1
We present multi-object spectroscopy of young, massive stars in the Local Group galaxy IC 1613. We provide the spectral classification and a detailed spectral catalog for 54 OBA stars in this galaxy. The majority of the photometrically selected sample is composed of Band A-type supergiants. The remaining stars include early O-type dwarfs and the only Wolf-Rayet star known in this galaxy. Among ...
متن کاملA catalogue of OB associations in IC 1613
We present a catalogue of OB associations in IC 1613. Using an automatic and objective method (Battinelli’s 1991 technique) 60 objects were found. The size distribution reveals a significant peak at about 60 parsecs if a distance modulus of 24.27 mag is assumed. Spatial distributions of the detected associations and H II regions are strongly correlated.
متن کاملthe impact of musical texts on the text recall of young learners of english in isfahan junior high schools
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
