Abstract:
OB-type stars have strong ionizing radiation and drive energetic
winds. The ultraviolet radiation from ionizing stars may heat dust and
ionize gas to sweep up an expanding bubble shell. This shell may be
the result of feedback leading to a new generation of stars.
N131 is an infrared dust bubble residing in a molecular filament. We
study the formation and fragmentation of this bubble with
multiwavelength dust and gas observations.
Towards the bubble N131, we analysed archival multiwavelength
observations including 3.6, 4.5, 5.8, 8.0, 24, 70, 160, 250, 350,
500um, 1.1mm, and 21cm. In addition, we performed new observations of
CO (2-1), CO (1-0), and 13CO (1-0) with the IRAM 30m telescope.
Description:
Integrated intensity maps of the CO (2-1), CO (1-0), and 13CO (1-0)
with velocity range from -14.5 to -6.5km/s. The CO (2-1), CO (1-0),
and 13CO (1-0) observations were simultaneously carried out during
2014 April 17-20 using the IRAM 30-m telescope 1 on Pico Veleta,
Spain. The E90 and E230 bands of the new Eight MIxer Receiver (EMIR)
covered the three lines. The receiver was tuned to cover the frequency
ranges 110.186 to 112.006GHz for 13 CO (1-0), 113.466 to 115.286GHz
for CO (1-0), and 229.678 to 231.498GHz for CO (2-1) observations. The
Fast Fourier Transform Spectrometer (FFTS) backends were set at 50kHz
resolution.
