Galactic cosmic ray-induced radiation dose on terrestrial exoplanets.
This past decade has seen tremendous advancements in the study of extrasolar planets. Observations are now made with increasing sophistication from both ground- and space-based instruments, and exoplanets are characterized with increasing precision. There is a class of particularly interesting exoplanets that reside in the habitable zone, which is defined as the area around a star where the pla...
متن کاملA Solar and Galactic Cosmic Ray Satellite Experiment
The three telescopes identify particle energy and type by various techniques. Energy loss and range, which provide the identification of protons (1 to 300 MeV), alpha particles (4 to 1200 MeV) and electrons (1 to 500 MeV), are measured in a stack of silicon solid state detectors and tungsten absorbers in the NE-Range telescope, while the identification of protons (350 to 1000 MeV), alpha partic...
متن کاملSolar Modulation on Galactic Cosmic Rays in the Earth’s Atmosphere
A brief review of solar modulation on galactic cosmic rays in the earth’s atmosphere is presented. The results of the characterizations of the major two events i.e. Galactic Cosmic Rays (GCRs)(measured in counts) and Galactic Solar rays(GSRs) (measured in counts) against time (measured in hour) shows significant variations. It was also observed that the variations of the events are slightly out...
متن کاملGalactic Cosmic Ray Modulation near the Heliospheric Current Sheet
Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ejections or the heliospheric current sheet, HCS). Due to the close association between the HCS, the streamer belt, and the band of slow solar wi...
متن کاملLong-Term Modulation of the Galactic Cosmic-Ray Fluctuation Spectrum
We study the temporal behavior of the power spectra for Galactic cosmic-ray fluctuations during the last two solar cycles. We use the 5-min data for 1980–2002 corrected for the barometric effect from two widely separated high-latitude cosmic-ray stations, Tixie Bay and Oulu. The cosmicray fluctuation spectrum is shown to be subjected to a regular long-term modulation with a period of about 11 y...
