• Habitable planets around the star Gliese 581 (2007, background): “In addition, Williams & Pollard (2002) show that habitability depends primarily on the average stellar flux received over an entire orbit, < S >, even at high eccentricity, and < S > depends on the eccentricity through the relationship: < S >= S√ 1 − e2 (5) where S is the stellar flux at the…”
• Tidal obliquity evolution of potentially habitable planets (2011, methodology): “…time and area on the Earth’s surface, is about 1000 W/m2 when the Sun is in the zenith3, the stellar incident flux on Gl581 d averaged over an orbit (Williams & Pollard 2002) is f = LGl581 4πa2 √ 1− e2 ≈ 432 W/m2, (28) with the luminosity of the host starLGl581 = 0.013L⊙ (Bonfils et al. 2005a;…”
• THE OCCURRENCE OF POTENTIALLY HABITABLE PLANETS ORBITING M DWARFS ESTIMATED FROM THE FULL KEPLER DATASET AND AN EMPIRICAL MEASUREMENT OF THE DETECTION SENSITIVITY (2015, background): “…high obliquities or eccentric orbits might be partially habitable at certain latitudes or during certain times of year (Williams & Kasting 1997; Williams & Pollard 2002; Spiegel et al. 2008, 2009; Dressing et al. 2010; Cowan et al. 2012; Dobrovolskis 2013; Armstrong et al. 2014; Linsenmeier et…”
• Debris disks as signposts of terrestrial planet formation (2011, background): “Given its large eccentricity, one would expect this planet’s climate to be highly variable during the year (Williams & Pollard 2002; Dressing et al. 2010).”
• The Habitability of Planets Orbiting M-dwarf Stars (2016, background): “Additionally, annually-averaged insolation increases with orbital eccentricity (Berger et al., 1993; Williams & Pollard, 2002; Berger et al., 2006), and modeling studies have shown that high-eccentricity planets exit episodes of global ice cover more easily (Spiegel et al., 2010).”
