• ASTEROSEISMOLOGY OF RED GIANTS FROM THE FIRST FOUR MONTHS OF KEPLER DATA: GLOBAL OSCILLATION PARAMETERS FOR 800 STARS (2010, methodology): “We also plot the frequency separation ratios δν0l/∆ν which, according to models, are expected to be largely insensitive to surface layer effects (Roxburgh & Vorontsov 2003; Ot́ı Floranes et al. 2005; Mazumdar 2005; Chaplin et al. 2005).”
• AN ANCIENT EXTRASOLAR SYSTEM WITH FIVE SUB-EARTH-SIZE PLANETS (2015, methodology): “…implementing a Bayesian scheme that uses the spectroscopic constraints and frequency ratios as the parameters in the fit (V. Silva Aguirre et al., submitted), the latter being almost insensitive to the surface effects in solar-like oscillators (Roxburgh & Vorontsov 2003; Silva Aguirre et al. 2011).”

• Standing on the Shoulders of Dwarfs: the Kepler Asteroseismic LEGACY Sample. II. Radii, Masses, and Ages (2016, methodology): “Another method is to fit combinations of frequencies, normally the frequency separation ratios, defined as (Roxburgh & Vorontsov 2003): r02(n) = d02(n) ∆ν1(n) (2) r01(n) = d01(n) ∆ν1(n) , r10(n) = d10(n) ∆ν0(n+ 1) .”
• A new correction of stellar oscillation frequencies for near-surface effects (2014, unknown): “Second, Roxburgh & Vorontsov (2003) suggested fitting models to observations using particular ratios of frequency differences, which have been used by several groups (e.g. Silva Aguirre et al. 2013) to fit stellar models.”
• Helioseismology and Solar Abundances (2007, background): “The frequency separation ratios (Roxburgh & Vorontsov 2003; Ot́ı Floranes et al. 2005; Roxburgh 2005) formed from the small frequency and large frequency spacings of the modes are given by r0,2(n) = δνn,0 ∆νn,1 , r1,3(n) = δνn,1 ∆νn+1,0 .”
• SOLAR-LIKE OSCILLATIONS IN LOW-LUMINOSITY RED GIANTS: FIRST RESULTS FROM KEPLER (2010, methodology): “(2) The spread of points about this relation presumably reflects a spread in stellar masses, and is better 4 T. R. Bedding et al. seen by plotting the ratio of the two separations, as shown in Figure 4b (see Roxburgh & Vorontsov 2003; Ot́ı Floranes et al. 2005; Mazumdar 2005).”
• MODULES FOR EXPERIMENTS IN STELLAR ASTROPHYSICS (MESA): PLANETS, OSCILLATIONS, ROTATION, AND MASSIVE STARS (2013, background): “Current developments in astero further seeks to overcome such problems and improve the robustness of the results by including frequency ratios (Roxburgh & Vorontsov 2003; Silva Aguirre et al. 2013) in the χ2 minimization.”
• NEW SOLAR COMPOSITION: THE PROBLEM WITH SOLAR MODELS REVISITED (2009, methodology): “Low-degree helioseismology (ℓ ≤ 3) can be used to derive seismic information on the solar core, particularly by using the so-called separation ratios as described by Roxburgh & Vorontsov (2003).”
