About this award
The National Aeronautics and Space Administration (NASA) Shared Services Center awarded a $98,495.00 grant to Carleton College, a private liberal arts college in Northfield, Minnesota, to conduct research on stellar magnetic activity and its effects on exoplanet detection through radial velocity measurements. The research aims to develop methods for directly measuring stellar magnetic fields in order to enable more precise calculations of exoplanet masses. This grant does not have a set-aside designation and is intended to provide a conclusive test of a method for measuring stellar magnetic fields to correct radial velocity variability, with the goal of informing future observations, instrumentation, or modeling efforts in this area of astrophysics research.
Description
Stellar magnetic activity confuses the interpretation of radial velocity (RV) measurements, impeding precise exoplanetary mass measurements. Spatially resolved magnetic field measurements have shown promise for correcting the effects of activity on the sun, but similar methods have not been demonstrated for disk-integrated light that would be applicable to other STARS. Aims: observe a small number of highly magnetically sensitive lines at ultra-high (r>106) resolution in disk-integrated sunlight to explore whether the magnetic field change is recoverable (FIG. 1), and whether this direct probe can inform and advance complementary techniques. A conclusive test of a simple method for measuring the stellar magnetic field to correct RV variability. This test will determine the resolution, signal-to-noise ratio, and temporal sampling requirements necessary to inform future observations or instrumentation, or IT will reveal the observational or modeling limitations of this approach. Either way, the reliably calibrated ultra-high resolution time series spectra of highly magnetically sensitive solar lines will be a powerful starting point for developing and testing the advanced magneto-hydrodynamical models that are required to accurately simulate solar/stellar spectra.
