A Systematic Observational Study on Galactic Interstellar Ratio 18O/17O. II. C18O and C17O J=2-1 Data Analysis
Y. P. Zou, J. S. Zhang, C. Henkel +7
To investigate the relative amount of ejecta from high-mass versus intermediate-mass stars and to trace the chemical evolution of the Galaxy, we have performed with the IRAM 30m an…
Interstellar Nitrogen Isotope Ratios: New NH3 Data from the Galactic Center out to the Perseus Arm
J. L. Chen, J. S. Zhang, C. Henkel +10
Our aim is to measure the interstellar 14N/15N ratio across the Galaxy, to establish a standard data set on interstellar ammonia isotope ratios, and to provide new constraints on t…
IRIS observations of chromospheric heating by acoustic waves in solar quiet and active regions
V. Abbasvand, M. Sobotka, M. Švanda +3
Aims: To study the heating of solar chromospheric magnetic and nonmagnetic regions by acoustic and magnetoacoustic waves, the deposited acoustic-energy flux derived from observatio…
Galactic interstellar sulfur isotopes: A radial SS gradient?
H. Z. Yu, J. S. Zhang, C. Henkel +9
We present observations of CS, CS, CS and CS J=21 lines toward a large sample of massive star forming regions by using th…
A systematic observational study on Galactic interstellar ratio 18O/17O: I. C18O and C17O J=1-0 data analysis
J. S. Zhang, W. Liu, Y. T. Yan +15
The interstellar oxygen isotopic ratio of 18O/17O can reflect the relative amount of the secular enrichment by ejecta from high-mass versus intermediate-mass stars. Previous observ…
Fermi-LAT Observations of High-energy Behind-the-limb Solar Flares
M. Ackermann, A. Allafort, L. Baldini +86
We report on the Fermi-LAT detection of high-energy emission from the behind-the-limb (BTL) solar flares that occurred on 2013 October 11, and 2014 January 6 and September 1. The F…
