Interplanetary shock data base
Frontiers in Astronomy and Space Sciences, 2023 In this manuscript, I provide an updated interplanetary shock data base I published in previous works. This list has now 603 events. I also present and describe the data and methodologies used to compile this list. The main contribution of this work is to provide an updated end accurate interplanetary shock data base for future space physics and space ...

Magnetic Cloud and Its Interplanetary Shock Sheath as a Modulator of the Cosmic Ray Intensity [PDF]
Journal of Astronomy and Space Sciences, 2008 Forbush Decreases (FDs) are representative events of abrupt decrease in galactic cosmic ray intensity. They are known to be strongly associated with solar wind events such as interplanetary shock (IP shock) and magnetic cloud (MC).

Drift acceleration at interplanetary shocks [PDF]
The Astrophysical Journal Supplement Series, 1994 AbstractScatter-free acceleration of energetic particles by quasi-perpendicular interplanetary shocks is investigated. A brief review is given on the predictions of the gradient drift acceleration model concerning the energy, time, and angular dependence of the particle flux caused by a single shock encounter interaction.

Transit of the Interplanetary Shocks Associated with Type II Radio Bursts Within 1AU [PDF]
Journal of Astronomy and Space Sciences, 2007 Among the interplanetary shock (IP shock)s observed by ACE spacecraft at 1AU during 1997 to 2000, we have selected 31 IP shocks which had triggered the interplanetary type II radio bursts detected by the WIND spacecraft while those shocks were leaving ...

Particle Acceleration at Interplanetary Shocks [PDF]
Space Science Reviews, 2007 This paper briefly reviews proton acceleration at interplanetary shocks. This is key to describing the acceleration of heavy ions at interplanetary shocks because wave excitation—and hence particle scattering—at oblique shocks is controlled by the protons and not the heavy ions.

Physical Characteristics of Coronal Region Driving Out the Interplanetary Shock [PDF]
Journal of Astronomy and Space Sciences, 2008 Using the solar wind data of 2000 observed by ACE, We classified the interplanetary shock on basis of shock driver. We examined the physical properties of shock drivers such as the ratio of charge states(O7/O6) and thermal index(I_{th}).

Long-duration high-energy proton events observed by GOES in October 1989 [PDF]
Annales Geophysicae, 1998 We consider the prolonged injection of the high-energy (>10 MeV) protons during the three successive events observed by GOES in October 1989. We apply a solar-rotation-stereoscopy approach to study the injection of the accelerated particles from ...

CLASSIFICATION OF THE INTERPLANETARY SHOCKS BY SHOCK DRIVERS [PDF]
Journal of The Korean Astronomical Society, 2002 From the data of solar wind observation by ACE spacecraft orbiting the Earth-Sun Lagrangian point, we selected 48 forward interplanetary shocks(IPSs) occurred in 2000, maximum solar activity period. Examining the profiles of solar wind parameters, the IPSs are classified by their shock drivers.

In situ local shock speed and transit shock speed [PDF]
Annales Geophysicae, 1998 A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

Interaction of a strong interplanetary shock with the termination shock [PDF]
Journal of Geophysical Research: Space Physics, 1999 The 1991 global merged interaction region (GMIR) shock is a strong forward shock observed from Voyager 2 on day 146 of 1991 at 34.6 AU. As the GMIR shock propagated out‐ward in the distant heliosphere, it eventually encounters the termination shock. We study the interaction of the GMIR shock with the termination shock taking into account the influence ...
