On the Relationship between Magnetic Expansion Factor and Observed Speed of the Solar Wind from Coronal Pseudostreamers
Samantha Wallace, Charles N. Arge, Nicholeen M. Viall +1
For the past 30+ years, the magnetic expansion factor () has been used in empirical relationships to predict solar wind speed () at 1 AU, based on an inverse relation…
Detection of 4765 MHz OH Emission in a Pre-Planetary Nebula -- CRL 618
A. Strack, E. D. Araya, M. E. Lebrón +8
Jets and outflows are ubiquitous phenomena in astrophysics, found in our Galaxy in diverse environments, from the formation of stars to late-type stellar objects. We present observ…
Quasi-simultaneous 43 and 86 GHz SiO Maser Observations and Potential Bias in the BAaDE Survey Are Resolved
Michael C. Stroh, Ylva M. Pihlström, Lorànt O. Sjouwerman +3
We observed the 43 GHz v=1, 2, and 3 and 86 GHz v=1 SiO maser transitions quasi-simultaneously for a Mira-variable-dominated sample of over 80 sources from the Bulge Asymmetries an…
Proper Motions of H2O Masers in the Water Fountain Source IRAS 19190+1102
F. M. Day, Y. M. Pihlstrom, M. J. Claussen +1
We report on the results of two epochs of Very Long Baseline Array (VLBA) observations of the 22 GHz water masers toward IRAS 19190+1102. The water maser emission from this object…
