COMPETENCES : ● Utilisation du théorème de Pythagore ● Utilisation de Google Earth pour évaluer des distances à vol d'oiseau ● Recherche personnelle de données REALISATION : Il s'agit ici de mettre en application le théorème de Pythagore mais avec une vision terrestre dans un premier temps suite à un questionnement de l'élève puis dans un second temps de réutiliser la même démarche dans le cadre spatial de la visibilité d'un satellite. Fiche élève ____________________________________________________________________________ 1. Victor Hugo a écrit dans Les Châtiments : "Les horizons aux horizons succèdent […] : on avance toujours, on n’arrive jamais ". Face à la mer, vous voyez l'horizon à perte de vue. Mais "est-ce loin, l'horizon ?". D'après toi, jusqu'à quelle distance peux-tu voir si le temps est clair ? Réponse 1 : " Sans instrument, je peux voir jusqu'à .................. km " Réponse 2 : " Avec une paire de jumelles, je peux voir jusqu'à ............... km " 2. Nous allons maintenant calculer à l'aide du théorème de Pythagore la ligne d'horizon pour une hauteur H donnée. -

Starshade Exoplanet Data Challenge: Data Release #3 Stuart Shaklan, Mario Damiano, Stefan Martin, Renyu Hu June 16, 2021 © 2021 All rights reserved. Government sponsorship acknowledged. CL # 21-2781 Data provided • For RST: • Simulated spectra of scenes with the starshade blocking the target star. • Simulated spectra of the stars (starshade moved away from the scene). • Line spread and dispersion function with 1 nm, 5 mas resolution. • For HabEX: • Simulated IFS spectra of scenes with the starshade blocking the target star. • Simulated IFS spectra of the stars (starshade moved away from the scene). • Mapping arrays from lenslet positions to image plane positions with a wavelength resolution of 1 nm. RST Spectroscopy Modeling Methodology • Follows the same approach that GSFC (N. Zimmerman) took for CGI: • Use a ray trace model of the prisms and lenses. Map Image plane (x,y,lambda) to output plane (x’,y’,lambda). • But for speed, we use a 3rd order approximation to the distortion map, which has < 0.5 mas error. • Treat the slit as a simple field stop: ignore diffraction since the slit is wide compared to the PSF • Input image plane is computed with a 5 mas pixel pitch • Highly oversamples PSF • Highly oversampled compared to final CGI pixel pitch of 21.8 mas/pixel • Map from input to output with 5 mas resolution • Bin to 21.8 mas resolution using Matlab ‘imresize’ routine. • Absolute position of spectra in image plane are not tracked, but relative position of spectra in the simulations are all consistent with the scenes. Line Spread Function and Dispersion • The dispersion is calculated every nm, and on a 5 mas pixel grid (compared to 21.8 mas pixels in the camera). -

We present an analysis of OGLE 2004–BLG–254, a high-magnification (A 60) and relatively short duration (tE 13.2 days) microlensing event in which the source star, a Bulge K-giant, has been spatially resolved◦ ≃ by a point-like lens. We seek to determine≃ the lens and source distance, and provide a measurement of the linear limb-darkening coefficients of the source star in the I and R bands. We discuss the derived values of the latter and compare them to the classical theoretical laws, and furthermore examine the cases of already published microlensed GK-giants limb-darkening measurements. -
Cycle 12 Abstract Catalog
Cycle 12 Abstract Catalog Generated April 04, 2003 ================================================================================ Proposal Category: GO Scientific Category: ISM AND CIRCUMSTELLAR MATTER ID: 9718 Title: SMC Extinction Curve Towards a Quiescent Molecular Cloud PI: Francois Boulanger PI Institution: Institut d'Astrophysique Spatiale The lack of 2175 A bump in the SMC extinction curve is interpreted as an absence of small carbon grains. ISO Mid-IR observations support this interpretation by showing that PAH features are absent in the spectra of SMC and LMC massive star forming regions. However, the only ISO observation of an SMC quiescent molecular cloud shows all PAH features, indicating a PAH abundance relative to large dust grains similar to that of Milky Way clouds. We identified a reddened B2III star associated with this cloud. We propose to observe it with STIS. This observation will provide the first measure of the extinction properties of SMC dust away from star forming regions. It will allow us to disentangle the effects of metallicity and massive stars on the SMC extinction curve and dust composition and to assess the relevance of the SMC bump-free extinction curve to low metallicity and/or starburst galaxies in general. ================================================================================ Proposal Category: GO Scientific Category: STELLAR POPULATIONS ID: 9719 Title: Search For Metallicity Spreads in M31 Globular Clusters PI: Terry Bridges PI Institution: Anglo-Australian Observatory Our recent deep HST photometry of the M31 halo globular cluster (GC) Mayall~II, also called G1, has revealed a red-giant branch with a clear spread that we attribute to an intrinsic metallicity dispersion of at least 0.4 dex in [Fe/H].
