Submillimeter observations of IC 10: the dust properties and neutral carbon content of a low metallicity starburst
We present submillimeter observations of the Local Group, metal-poor, irregular dwarf galaxy IC 10, directly relevant to the interaction between interstellar medium and star formation activity in primeval galaxies. Using the JCMT, we have observed the fine structure neutral carbon transition P1 → P0 at 492 GHz and the rotational J = 3 → 2 transition of CO and CO in the most massive giant molecu...

چکیده یکی از پارامترهای اصلی در دنبال کردن تاریخچه ی تشکیل ستاره ها و تحول کهکشان ها، مطالعه ی میزان فراوانی عناصر آن ها است. در این پایان نامه برای مطالعه ی همبستگی میان فراوانی فلزی و جرم ستاره ای کهکشان ها، از داده های طیفی 89 کهکشانِ ستاره زا استفاده شده است. طیف ها توسط طیف نگار فورس2 از میدان ژرف جنوبی چاندرا گرفته شده و جابه جایی به سرخ طیف ها همه بزرگتر از نیم و کوچکتر از یک هستند. جر...

We present submillimeter observations of the Local Group, metal-poor, irregular dwarf galaxy IC 10, directly relevant to the interaction between interstellar medium and star formation activity in primeval galaxies. Using the JCMT, we have observed the ne structure neutral carbon transition 3 P 1 ! 3 P 0 at 492 GHz and the rotational J = 3 ! 2 transition of 12 CO and 13 CO in the most massive gi...
متن کاملNew beryllium observations in low-metallicity stars
We present observations of the Be II 313.0 nm resonance doublet in 14 halo and old disk stars with metallicities ranging from [Fe/H]=-0.4 to≈-3.0 obtained with the CASPEC spectrograph of the ESO 3.6m telescope at a FWHM≈ 8.6 kms−1 resolution. Abundances are derived bymeans of the synthetic spectra technique employing Kurucz (1993) atmospheric models, with enhanced α-elements and no overshooting...
متن کاملTo appear in ApJ Dust in an extremely metal-poor galaxy: mid-infrared observations of SBS
The metal deficient (Z = Z⊙/41) Blue Compact Dwarf Galaxy (BCD) SBS0335-052 was observed with ISOCAM between 5 and 17μm. With a L12μm/LB ratio of 2.15, the galaxy is unexpectedly bright in the mid-infrared for such a low-metallicity object. The mid-infrared spectrum shows no sign of the Unidentified Infrared Bands, which we interpret as an effect of the destruction of their carriers by the very...
