Molecular Clouds Around a Run-away O Star, ζ Oph
Molecular clouds around a run-away O star ζ Oph have been surveyed with NANTEN telescope and their streaming motion caused by ζ Oph has been detected. ζ Oph is the earliest (O9.5V) member of the Sco OB2 association and is a runaway star rapidly moving accompanied by an H II region S27. We detected 2 major filamentary cloud complexes; one complex including L156 (L156 complex) is lying across nea...

Molecular clouds around a run-away O star ζ Oph have been surveyed with NANTEN telescope and their streaming motion caused by ζ Oph has been detected. The earliest (O9.5V) member of Sco OB2 association, ζ Oph, is a runaway star rapidly moving accompanied by an HII region S27. We detected 2 major filamentary cloud complexes; L156 complex is lying across nearly the center of S27 and the other one...
متن کاملImaging galactic diffuse clouds: CO emission, reddening and turbulent flow in the gas around ζ Oph
Context. Most diffuse clouds are only known as kinematic features in absorption spectra, but those with appreciable H2 content may be visible in the emission of such small molecules as CH, OH, and CO. Aims. We interpret in greater detail the extensive observations of 12CO emission from diffuse gas seen around the archetypical line of sight to ζ Oph. Methods. The 12CO emission is imaged in posit...
متن کاملRadio and submillimetre observations of wind structure in ζ Pup
We present radio and submillimetre observations of the O4I(n)f star ζ Pup, and discuss structure in the outer region of its wind (∼ 10 − 100 R *). The properties of bremsstrahlung, the dominant emission process at these wavelengths, make it sensitive to structure and allow us to study how the amount of structure changes in the wind by comparing the fluxes at different wavelengths. Possible form...
متن کاملthe problem of divine hiddenness
این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...
