MAGNETOHYDRODYNAMIC WAVES AND CORONAL HEATING: UNIFYING EMPIRICAL AND MHD TURBULENCE MODELS (2012, background): “Introduction Results from Hinode observations have recently upped the estimates for the MHD wave energetics in the solar corona (De Pontieu et al. 2007).”
ON-DISK COUNTERPARTS OF TYPE II SPICULES IN THE Ca ii 854.2 nm AND Hα LINES (2009, methodology): “This is similar to what De Pontieu et al. (2007c) observed in type II spicules.”
HEATING OF THE SOLAR CHROMOSPHERE AND CORONA BY ALFVÉN WAVE TURBULENCE (2011, methodology): “The chromosphere is highly dynamic, and is filled with jet-like features such as mottles and dynamic fibrils on the solar disk (Rouppe van der Voort et al. 2007; De Pontieu et al. 2007a) and spicules at the limb (De Pontieu et al. 2007b).”
Multiwavelength Studies of MHD Waves in the Solar Chromosphere (2015, background): “More recently, there has been the sub-classification of spicules into Type-I and Type-II varieties (De Pontieu et al. 2007b).”
The Volume-limited A-Star (VAST) survey – I. Companions and the unexpected X-ray detection of B6–A7 stars (2011, background): “…required to maintain the corona at temperatures greater than 106 K was originally thought to be acoustic waves (e.g. Schwarzschild 1948; Schatzman 1949), while current models involve Alfvén waves travelling perpendicular to the magnetic field (e.g. De-Pontieu et al. 2007; Jess et al. 2009).”
Standing Slow-Mode Waves in Hot Coronal Loops: Observations, Modeling, and Coronal Seismology (2010, background): “…in the time series of Doppler images (Tomczyk et al. 2007; Tomczyk & McIntosh 2009), transverse waves in threadlike structure of solar prominences (Okamoto et al. 2007; Ning et al. 2009), and the transverse oscillation of spicules in the chromosphere (De Pontieu et al. 2007; He et al. 2009a,b).”
PROPAGATING WAVES ALONG SPICULES (2011, methodology): “Because we require at least one full “wiggle” (i.e., a half period) during the spicule lifetime, we cannot measure the propagation or properties of the lower frequency waves (P > 100 s) that carry much more energy (De Pontieu et al. 2007a).”
The Interface Region Imaging Spectrograph (IRIS) (2012, background): “An instrument with these properties should be able to, e.g., quantify the properties of the waves that permeate this interface region (De Pontieu et al., 2007a; McIntosh et al., 2011; Okamoto and De Pontieu, 2011; De Pontieu et al., 2012; McIntosh and De Pontieu, 2012; Sekse et al., 2013) and…”
Oscillations and Waves in Solar Spicules (2009, methodology): “Indeed, Hinode/SOT observations (De Pontieu et al. (2007a)) show some evidence of upward and downward propagating waves, with some partially standing waves being observed.”
TIME–DISTANCE SEISMOLOGY OF THE SOLAR CORONA WITH CoMP (2009, background): “When considering the efficiency of these waves in heating the corona, or driving the solar wind (De Pontieu et al. 2007), we must explore this damping process further, consider the origins of the observed large non-thermal line widths in the corona and exploit the developing self-consistent…”
THREE-DIMENSIONAL MODELING OF QUASI-HOMOLOGOUS SOLAR JETS (2010, background): “The Sun exhibits jet-like events on a vast range of scales: photospheric spicules (e.g., Tziotziou et al. 2003; Pontieu et al. 2007); chromospheric Hα surges (e.g., Schmahl 1981; Schmieder et al. 1995; Canfield et al. 1996; Chen et al. 2008); chromospheric Ca ii H jets (e.g., Nishizuka et al. 2008;…”
STEREO SECCHI Stereoscopic Observations Constraining the Initiation of Polar Coronal Jets (2008, background): “The wave-like motions we observed could be related to the transverse oscillations detected in some jets (Cirtain et al. 2007), spicules (De Pontieu et al. 2007) and prominences (Okamoto et al. 2007).”
Solar Fine-Scale Structures. I. Spicules and Other Small-Scale, Jet-Like Events at the Chromospheric Level: Observations and Physical Parameters (2012, methodology): “De Pontieu et al. (2007c) analyzed time series of Ca ii H images taken with a SOT broadband filter.”
