Summary
[edit]DescriptionMWC 349 A.jpg |
English: Like lasers in visible light, masers are amplified electromagnetic waves in the microwave wavelengths. We use masers generated by hydrogen to probe the physical and dynamic structures in the gas surrounding star MWC 349A, which is about 30 times the mass of the Sun. Analysis of observations with the Atacama Millimeter/submillimeter Array revealed a flattened gas disk with a diameter of 50 au, approximately the size of the solar system, and a wind moving away from the star at a speed of 500 km/s, possibly launched by the magnetic force. |
