• Cold Disks: Spitzer Spectroscopy of Disks around Young Stars with Large Gaps (2007, background): “The earliest example discovered withSpitzer was CoKu Tau 4, modeled to have an inner hole within 10 AU (Forrest et al. 2004; D’Alessio et al. 2005).”
• EMPIRICAL CONSTRAINTS ON TURBULENCE IN PROTOPLANETARY ACCRETION DISKS (2010, methodology): “We use these two classes of models because they are well established and have been successful in describing the observed structure of circumstellar disks across a wide range of wavelengths, particularly in the submillimeter (see, e.g., Calvet et al. 2002, 2005; Andrews et al. 2009).”
• Dust dynamics during protoplanetary disc clearing (2007, background): “…and a handful of " transitional " discs, with properties between the CTT and WTT states, have now been well-studied (e.g. GM Aur, Rice et al. 2003; Calvet et al. 2005; TW Hya, Calvet et al. 2002; Eisner, Chiang & Hillenbrand 2006; CoKu Tau/4, Forrest et al. 2004; d'Alessio et al. 2005a).”
• Observational Signatures of Planets in Protoplanetary Disks I: Gaps Opened by Single and Multiple Young Planets in Disks (2014, background): “Discovered through their unique infrared deficit from NIR to ∼ 10 µm, which signals a lack of warm dust in the inner disk (Calvet et al. 2005; Espaillat et al. 2007, 2010), these disks have been subsequently shown to harbor large gaps or cavities with sizes often up to tens of AU in spatially…”
• The Disk Around CoKu Tauri/4: Circumbinary, Not Transitional (2008, background): “Radial velocity monitoring is most applicable to DM Tau, where the cleared inner hole is expected to have only a 3AU radius (Calvet et al. 2005).”
• THE ROLE OF MULTIPLICITY IN DISK EVOLUTION AND PLANET FORMATION (2011, background): “A few such systems have been known since the 1980s (Strom et al. 1989; Skrutskie et al. 1990), but there are now several dozen such stars (Forrest et al. 2004; Calvet et al. 2005; Espaillat et al. 2007; Cieza et al. 2010).”
• Gas and Dust Emission at the Outer Edge of Protoplanetary Disks (2008, background): “Piétu et al. (2005) present multiwavelength millimeter continuum and CO isotopologue observations of the disk around the Herbig Ae star AB Aurigae and found from fitting models of disk structure described by truncated power laws that the outer radius of the dust derived from continuum emission (350”
• The Disk Population of the Chamaeleon I Star-forming Region (2008, background): “SEDs of this kind are indicative of disks with inner holes, which are also known as transitional disks (Calvet et al. 2002, 2005; D’Alessio et al. 2005; Espaillat et al. 2007a,b; Furlan et al. 2007).”
• TRANSITIONAL AND PRE-TRANSITIONAL DISKS: GAP OPENING BY MULTIPLE PLANETS? (2010, background): “10µm appears to be due entirely to optically-thin dust (Calvet et al. 2002, 2005; Espaillat et al. 2010).”
• Disk Evolution in Cep OB2: Results from the Spitzer Space Telescope (2006, background): “…strong decline in the frequency of these disk signatures between 1 and 10 Myr (Strom et al. 1989; Skrutskie et al. 1990; Hillenbrand et al. 1998; Lada et al. 2000;Muzerolle et al. 2000; Haisch et al. 2001; Briceño et al. 2001; Sicilia-Aguilar et al. 2005b, hereafter Paper II; Calvet et al. 2005).”
• Ring shaped dust accumulation in transition disks (2012, background): “They still present relatively high accretion rates (∼ 10−8M yr−1; see e.g.,Calvet et al. (2005); Espaillat et al. (2007)) which implies that the inner cavity is not completely empty and that some gas flows through the gap.”
• A Survey and Analysis of Spitzer Infrared Spectrograph Spectra of T Tauri Stars in Taurus (2006, background): “An extreme example is DM Tau (Calvet et al. 2005), which is an accreting T Tauri star but has no near-IR excess.”
• A Spitzer Space Telescope Study of Disks in the Young σ Orionis Cluster (2007, background): “Of particular interest are ‘‘transition disk’’ objects, which have an inner, optically thin disk region, possibly produced by planet clearing, combinedwith an outer, optically thick disk (Calvet et al. 2002, 2005; D’Alessio et al. 2005b; Megeath et al. 2005a).”
• TRANSITIONAL DISKS AS SIGNPOSTS OF YOUNG, MULTIPLANET SYSTEMS (2011, background): “For comparison, Calvet et al. (2005) estimate τ ∼ 0.002 at 10 µm.”
• RESOLVED IMAGES OF LARGE CAVITIES IN PROTOPLANETARY TRANSITION DISKS (2011, methodology): “Those data were supplemented with shorter baseline observations in the compact (C: baseline lengths of 6-70m) and extended (E: baseline lengths of 28-226m, excluding RX J1615-3255) configurations over the past year (since 2009 October), as were additional observations of GM Aur (C, E), LkHα 330 (C),”
• Dust filtration at gap edges: Implications for the spectral energy distributions of discs with embedded planets (2006, background): “…1992; Koerner, Sargent & Beckwith 1993; Rice et al. 2003), CoKu Tau/4 (Forrest et al. 2004; Quillen et al. 2004; D’Alessio et al. 2005) and DM Tau (Calvet et al. 2005), present spectral energy distributions (SEDs) that combine little excess flux (above the photospheric level) at nearIR…”
• THE DISK POPULATION OF THE UPPER SCORPIUS ASSOCIATION (2012, background): “A pre-transitional disk and a transitional disk have gaps and holes in their dust distributions, respectively, that are large enough to noticeably affect their SEDs (∆Rgap > 5 AU, Rhole > 1 AU, Strom et al. 1989; Calvet et al. 2005; Espaillat et al. 2007, 2010).”
• Gas density drops inside dust cavities of transitional disks around young stars observed with ALMA (2015, background): “High accretion rates (∼ 10−8 M⊙ yr−1, e.g. Calvet et al. 2005; Najita et al. 2007) indicate that the dust cavities are not empty, but gas is still flowing through the gap.”
• Spitzer Observations of the Orion OB1 Association: Disk Census in the Low-Mass Stars (2007, methodology): “…two categories: ‘‘transitional disks candidates,’’ which have an inner, optically thin disk region combined with an outer, optically thick disk (e.g., Calvet et al. 2002, 2005b); and ‘‘evolved disk objects,’’ in which there is an overall decrease of emission both the inner and outer regions of…”
