  8. Young Stellar Objects • From Circumstellar.org catalogue

  9. Young Stellar Objects • N band : 4-7 sources >=18-20Jy, observable with ATs38 sources >=1Jy, observable with UTs • L band : 18 sources >=2Jy, observable with ATs53 sources >=0.1Jy, observable with UTs • By an increase of the sensitivity to the coherent • flux by a factor of 5 : • N band AT : 20 sources instead of 2-4 • N band UT : 70 sources instead of 38 • L band AT : 40 sources instead of 18 • L band UT : 61 sources instead of 53

  11. Several Scenarios studied for different disk structures and dust contents Scenario 1. Flared disk, inner radius of 3 AU. Herbig source. The disk inclination is 45°. Scenario similar to the one used during Phase A for reconstructing an image. • Scenario 2 = scenario 1 with a disk inner radius of 4 AU • Scenario 3 = scenario 1 with a disk inclination of 35° • Scenario 4 = scenario 1 with a maximum grain size three times larger. • Scenario 5 = scenario 1 where the dust grains are made up also with 10% of crystalline olivine + Forsterite material. Images for several wavelengths are computed. • Scenario 6 = scenario 5, the same case as previously where the dust grains are made up also with a percentage of crystalline material but now the olivine composed grains are distributed for R <= 6 AU. • Scenario 7 : a puffed inner region as an alternative to Scenario 1. • Scenario 8 : a case with the presence of water ice grains (to be compared with scenario 1), disk without ice grains).

  12. 7 nights, 4 telescopes, N band Case 1: 10 % error on V, 0.1 rad on the closure phases. Case 2: 2-3% error on V, 0.01 rad on the closure phases.

  14. • Improvement of VLTI sensitivity and accuracy. • Sensitivities with MATISSE will be improved by : • - the use of an external Fringe Tracking, On and Off Axis, • - the continuation of the effort made to reduce the fast OPD jitters/ vibrations. • Accuracies with MATISSE will be improved by : • - the use of an external Fringe Tracking, • - the effort made to reduce the fast OPD jitters/ vibrations, • - the pupil lateral motion monitoring, • - the use of OPD jitter residuals, tip-tilt residual, pupil lateral motion information • when analysing the data. • High limiting magnitude : Urgent need to develop and test « exotic » modes : • H-K blind + N fringe-tracking • MR blind recording • New ideas for coherencing • High dynamic range : Urgent need to open the AMBER BCD

  15. Vers une ANR 2011 • Formation et Evolution des Systèmes Planétaires • 2 Axes afin d’apporter de nouveau résultats dans le domaines : • a) R&D codes Astrophysiques (différent types poussière, région puffed-up, …) • b) R&D Traitement du signal (cas objet faible en régime ‘fond thermique’) • Projets : MIDI, AMBER (déjà utilisables), SPHERE (à court terme), …, • MATISSE & SPICA dont on a intérêt à préparer au mieux les programmes • Date de soumission : 10 (?) Janvier 2011, ANR sur 4 ans nous conduisant à l’intégration finale et aux tests de MATISSE. • Imaginé demandé : 2 post-doc, 2 Thèses, 50-100 k€ MATISSE & SPICA • Interface avec recherche et/ou ANR : corps mineurs, simulation dynamique, reconstruction d’image

  27. Science Programs and their key Issues ???????

  28. MATISSE Characteristics • Number of beams : four, two and three also possible. • Spectral coverage : L, M, N, possible also simultaneously. Optimized for L and N. • Spectral resolution : • low : 20 <R<40 in L&M at 3.5 mm; 20<R<40 in N at 10.5 mm. • Medium : 350<R<550 in L&M at 3.5 mm; 150<R<250 in N at 10.5 mm. • High : 800<R<1000 in L at 3.5 mm • The simultaneous coverage of theL&M bands in low and medium resolutions, and the full coverage of the L band in high spectral resolution require an external fringe tracker. • MATISSE will measure: coherent flux, visibilities, closure phases and differential phases. Differential visibilities can also be derived.

  29. MATISSE Observing Modes • 2 main modes • High sensitivity Mode (High Sens) : • 2T, 3T or 4T • With dedicated sequence of photometry: the photometry is evaluated by two means, • In the Fourier domain, by the low frequency peak, • Using dedicated long sequences of photometric recording. • Without photometry => Phase Oriented Mode • Simultaneous Photometry Mode (Si Phot) : • 2T, 3T or 4T • Photometric channels are used, individual photometry is estimated frame by frame for bright targets, or binned relatively to the chopping frequency.
