The Physical Processes of CME/ICME Evolution (2017, methodology): “The cessation distance of ICME rapid deceleration (about 50 and 85 R for the 7 March 2012 and 12 December 2008 CMEs, respectively) is much shorter than the average cessation distance of 0.76 AU (163 R ) inferred indirectly by Gopalswamy et al. (2001b).”
CONNECTING SPEEDS, DIRECTIONS AND ARRIVAL TIMES OF 22 CORONAL MASS EJECTIONS FROM THE SUN TO 1 AU (2014, background): “Especially for very fast CMEs, these speeds will not match the speeds measured in situ at 1 AU because of the CME deceleration that occurs up to 1 AU (e.g. Gopalswamy et al. 2001; Vršnak et al. 2013).”
Properties of Interplanetary Coronal Mass Ejections (2007, methodology): “They found similar results (92–93% association) for an expanded data set (Gopalswamy et al., 2001a).”
Space weather: the solar perspective (2021, methodology): “It is well known that CMEs during their propagation phase tend to get adjusted to the ambient solar wind flow owing to the drag force exerted by the ambient solar wind (Gopalswamy et al. 2001a; Wang et al. 2004).”
A survey of interplanetary coronal mass ejections in the near-Earth solar wind during 1996-2002 (2003, background): “…rates and initial speeds as a function of Vmax or transit speed from the results in Figure 1 by making a simple assumption such as a constant acceleration/deceleration rate in the solar wind [e.g., Gopalswamy et al., 2001], such an assumption is questionable; we have not pursued this further.”
A Statistical Study of Two Classes of Coronal Mass Ejections (2002, methodology): “Extensive discussions on the interaction between CMEs and the solar wind are presented in Gopalswamy et al. (2000, 2001a).”
Coronal mass ejections and other extreme characteristics of the 2003 October–November solar eruptions (2005, methodology): “The model was an extension of the empirical CME arrival model [ Gopalswamy et al., 2001c ] based on the shock standoff distance from the driving CME, implied by gas dynamics.”
Deriving the radial distances of wide coronal mass ejections from elongation measurements in the heliosphere - application to CME-CME interaction (2009, background): “Fast CMEs are not expected to experience large acceleration in the heliosphere (e.g. Gopalswamy et al., 2001; Tappin, 2006).”
Solar source of the largest geomagnetic storm of cycle 23 (2005, background): “is not too different from what is expected from the linear relationship between the acceleration (a) and CME speed (V) near the Sun [see Gopalswamy et al., 2001 ]: a (ms � 2 )=”
The association of coronal mass ejections with their effects near the Earth (2005, methodology): “Further studies (e.g. Webb et al., 2000; Cane et al., 2000; Gopalswamy et al., 2001c; Vršnak and Gopalswamy, 2002; Michalek et al., 2002; González- Esparza et al., 2003a,b; Yurchyshyn et al., 2003) tried to improve the prediction accuracy, but they all keep suffering from the problem of deducing…”
S/WAVES: The Radio and Plasma Wave Investigation on the STEREO Mission (2008, neutral): “(3) The relationship of burst “hotspots” to CMEs, shocks, interactions between several CMEs and solar wind structures (cf. Reiner et al. 1998a; Gopalswamy et al. 2001a; Knock and Cairns 2005) will be firmly established and quantified using S/WAVES direction-finding capabilities and data-driven…”
Kinematics of coronal mass ejections between 2 and 30 solar radii. What can be learned about forces governing the eruption (2004, background): “The slopes from Gopalswamy et al. (2000) and Gopalswamy et al. (2001b) are drawn at R = 40 and R = 46, respectively, corresponding to the geometrical mean (see the argumentation in Vršnak 2001a) of the considered distance ranges (0.76 and 1 au, respectively).”
The SOHO/LASCO CME Catalog (2009, background): “The 900 km/s is not a magic number: it is based on the average speed of CMEs that produce interplanetary type II radio bursts (Gopalswamy et al. 2001b).”
A statistical study on the geoeffectiveness of Earth‐directed coronal mass ejections from March 1997 to December 2000 (2002, methodology): “It should be noted that the transit time used here was not the same as the other transit times which have been used in different authors’ works [e.g., Gopalswamy et al., 2000, 2001a; Cane et al., 2000].”
