Forbich, Berger, and Reid attempt to use a large radio array to detect stellar wobbles induced by orbiting planets at larger separations than are usually probed
The mass of a substellar companion can help determine whether it’s a planet or a brown dwarf. But how can you measure the mass of a companion that you can’t detect directly? Look at the disk!
I went back to school this summer – at 7,000 feet with scorpions and Fourier Transforms.
Improving stellar astrophysical measurements will help us to better characterize exoplanets. The interferometric observational techniques applied here allow scientists to precisely measure the stellar parameters (including star’s radius) of a nearby system with exoplanets, including a transiting super-Earth.
