cds-question@unistra.fryoung-stellar-objectsinfrared-photometrystellar-massesline-intensitiesIn this work, we introduce the use of HI Pfund {beta} (Pf{beta}; 4.6538{mu}m) as a tracer of mass accretion from protoplanetary disks onto young stars. Pf{beta} was serendipitously observed in NIRSPEC and CRIRES surveys of CO fundamental emission, amounting to a sample size of 120 young stars with detected Pf{beta} emission. Using a subsample of disks with previously measured accretion luminosities, we show that Pf{beta} line luminosity is well correlated with accretion luminosity over a range of at least three orders of magnitude. We use this correlation to derive accretion luminosities for all 120 targets, 65 of which are previously unreported in the literature. The conversion from accretion luminosity to accretion rate is limited by the availability of stellar mass and radius measurements; nevertheless, we also report accretion rates for 67 targets, 16 previously unmeasured. Our large sample size and our ability to probe high extinction values allow for relatively unbiased comparisons between different types of disks.2013ApJ...769...21Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/769/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/237 : Stellar Photometry in Johnson's 11-color system (Ducati, 2002)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)II/62 : Catalogue of Extinction Data (Neckel+, 1980)J/ApJS/186/259 : Taurus Spitzer survey: new candidate members (Rebull+, 2010)J/A+A/508/309 : Spectral atlas of HD 50138 (Borges Fernandes+, 2009)J/ApJS/181/321 : Properties of Spitzer c2d dark clouds (Evans+, 2009)J/ApJ/703/1964 : Spectra of three nearby star-forming regions (Furlan+, 2009)J/ApJS/177/551 : Spitzer c2d survey of Lupus dark clouds (Merin+, 2008)J/ApJ/667/308 : Weak-line T Tauri in Spitzer c2d Survey.
