J/A+A/365/90               NIR H lines in TTS                     (Folha+, 2001)

Near infrared hydrogen lines as diagnostic of accretion and winds in T Tauri Stars Folha D.F.M., Emerson J.P. <Astron. Astrophys. 365, 90 (2001)> =2001A&A...365...90F
ADC_Keywords: Stars, pre-main sequence ; Radial velocities ; Spectra, infrared ; Equivalent widths Keywords: line: profiles - circumstellar matter - stars: formation - stars: pre-main sequence - infrared: general - infrared: stars Description: Paschen β and/or Bracket γ emission line profiles were obtained for a sample of 50 T Tauri stars mostly from the Taurus-Auriga complex. The tables presented here contain the computed line parameters of the observed line profiles. File Summary:
