PI: Dr. Lynne A. Hillenbrand California Institute of Technology Y CoI: Dr. Gregory J. Herczeg Peking University N CoI: Prof. Kevin France University of Colorado at Boulder N CoI: Adolfo Carvalho California Institute of Technology N ------------------------------------------------------------------------------------ Abstract FU Ori stars are a rare class of young stellar object, with less than two dozen examples known. Yet the long-lasting FU Ori outburst events play a prominent role in our understanding of stellar mass assembly at the individual star level. The currently favored model is that of an inner disk instability causing a factor of 100-10, 000 increase in the disk-to-star accretion rate. Ultraviolet observations are the most direct way to test the accretion disk scenario -- by measuring the hottest part of the inner disk and thereby determining physical parameters such as temperature T_max and temperature profile T(R). We propose here a complete STIS+COS legacy spectrum for the prototype of the class, FU Ori itself (11 orbits), plus a STIS low-resolution NUV spectral survey for four additional FU Ori outbursts (10 orbits). Heating by viscous accretion will be tested by (1) comparing the new data on FU Ori to a previous STIS spectrum obtained 20 years ago, to look for evidence of disk cooling, and (2) comparing the maximum disk temperature across the five targets, which span a factor of 6 in luminosity. These tests can only be done in the NUV, which is sensitive to the hottest disk temperatures. The spectra will be interpreted using a new empirical disk model that has been applied successfully to longer wavelength observations of FU Ori stars. This survey of extreme accretion disks provides an important complement to the ULLYSES DD Spectroscopic Legacy Project, developed to evaluate magnetospheric accretion on typical T Tauri stars. Our program focuses on the extreme state of accretion physics for young stars, with importance for the evolution of the star and the disk. ------------------------------------------------------------------------------------ Observations Description ------------------------ FU Ori: STIS G430L, G230L, G140L (in two orbits) plus E230M (in 5 orbits) FU Ori, COS: G130M and G160M (4 orbits) Five other targets: G230L and quick G430L spectra (2 orbits total) Optical peakups are based on a flux-calibrated spectrum of V2493 Cyg, scaled to recent ASAS-SN g-band photometry of all targets. The COS acquisition of FU Ori uses MIRRORB and is estimated from a previous E140M spectrum, but scaled down according to V-band decline over past 20 years. 17176( 8) - 12-Jun-2024 18:32:27 - [ 2] Count rates are provided for acquisitions and the COS FUV spectra. Sources are not highly variable, so the count rates should be accurate to within a factor of ~2. Spectra for count rates: 1) Optical: used V2493 Cyg, scaled to appropropriate flux using recent ASAS-SN g-band photometry 2) near-UV: used an old STIS E230M spectrum of FU Ori 3) far-UV, two choices: (a) V836 Tau COS, scaled for C IV emission that may have been detected in IUE spectrum of FU Ori (b) flat spectrum with flux of FU Ori from continuum (estimated from IUE, may not be significant) The targets are all far lower than the bright limits of COS and the STIS MAMA detectors. ------------------------------------------------------------------------------------ 17176( 8) - 12-Jun-2024 18:32:27 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-FU-ORI EXT-STAR, FU ORIONIS RA=05H45M22.3674S +/- 0.00001", J2000 V = 9.6 STAR DEC=+09D04'12.25" +/- 0.00001" Reference Frame: ICRS Extended: NO Comments: RA and Dec from Gaia DR3 g=10.6 in ASAS-SN Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2015.5 1.6472635698406437E-4 -0.0025099999999999996 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 2 EM-LKHA-190 EXT-STAR, FU ORIONIS RA=20H58M53.7296S, J2000 V = 15.6 STAR DEC=+44D15'28.33" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. g=13.6 from ASAS-SN Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2015.5 -2.59981026337079E-4 -0.003812999989349919 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 3 V-V960-MON EXT-STAR, FU ORIONIS RA=06H59M31.5877S, J2000 V = 14.94 STAR DEC=-04D05'27.77" Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. g=13.5 from ASAS-SN Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2015.5 -8.468244234726461E-5 -2.54999963544833E-4 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 4 V-V646-PUP EXT-STAR, FU ORIONIS RA=07H50M35.5873S, J2000 V = 12.65 STAR DEC=-33D06'23.83" Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. g=13.5 from ASAS-SN Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2015.5 -3.2710339565449645E-4 0.00501 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 17176( 8) - 12-Jun-2024 18:32:27 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 5 V-V2493-CYG EXT-STAR, FU ORIONIS RA=20H58M17.0274S, J2000 V = 13.5 STAR DEC=+43D53'43.29" Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
