Description

Cosmic rays striking the solar atmosphere are expected to produce particle showers, which will result in the generation of gamma-rays and neutrinos. Following current evidence for high-energy gamma rays originating from the solar disk, a first search for high-energy neutrinos from the Sun with 7 years (2010-2017) of IceCube data was recently completed, observing no significant signal. We present the results of a new and improved successor search for solar atmospheric neutrinos, making use of an improved likelihood method, a newer high-energy track dataset with additional years and better event reconstruction, leading to a sixfold improvement in sensitivity. We also present a time-dependent look at the flux during the solar minimum, motivated by an observed anti-correlation between solar activity and solar high-energy gamma ray flux during past solar cycles.
