چکیده
Solar observations of carbon monoxide (CO) indicate the existence lower-temperature gas in lower solar chromosphere. We present an observation pores, and quiet-Sun, network magnetic field regions with CO 4.66 {\mu}m lines by Cryogenic Infrared Spectrograph (CYRA) at Big Bear Observatory. used strong around to understand properties thermal structures atmosphere different features various strengths. AIA 1700 {\AA} images, HMI continuum images magnetograms are also included observation.

Aims. A study of 12 ultracompact HII regions was conducted to probe the physical conditions and kinematics in the inner envelopes of the molecular clumps harboring them. Methods. The APEX telescope was used to observe the sources in the CO (4–3) and 13 CO (8–7) lines. Line intensities were modeled with the RATRAN radiative transfer code using power laws for the density and temperature to descri...
متن کاملObservations of Dicke narrowing and speed dependence in air-broadened CO₂ lineshapes near 2.06 μm.
Frequency-stabilized cavity ring-down spectroscopy was used to study CO2 lineshapes in the (20013) ← (00001) band centered near 2.06 μm. Two rovibrational transitions were chosen for this study to measure non-Voigt collisional effects for air-broadened lines over the pressure range of 7 kPa-28 kPa. Lineshape analysis for both lines revealed evidence of simultaneous Dicke (collisional) narrowing...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
