Abstract
Thermal images of cold dust in the Central Molecular Zone of the Milky Way, obtained with the far-infrared cameras on board the Herschel satellite, reveal a ˜3 x 107 M◦. ring of dense and cold clouds orbiting the Galactic center. Using a simple toy model, an elliptical shape having semi-major axes of 100 and 60 pc is deduced. The major axis of this 100 pc ring is inclined by about 40° with respect to the plane of the sky and is oriented perpendicular to the major axes of the Galactic Bar. The 100 pc ring appears to trace the system of stable x2 orbits predicted for the barred Galactic potential. Sgr A* is displaced with respect to the geometrical center of symmetry of the ring. The ring is twisted and its morphology suggests a flattening ratio of 2 for the Galactic potential, which is in good agreement with the bulge flattening ratio derived from the 2MASS data.

Using a simple toy model, an elliptical shape having semi-major axes of 100 and 60 pc is deduced. The major axis of this 100 pc ring is inclined by about 40° with respect to the plane of the sky and is oriented perpendicular to the major axes of the Galactic Bar. The 100 pc ring appears to trace the system of stable x<sub>2</sub> orbits predicted for the barred Galactic potential. Sgr A* is displaced with respect to the geometrical center of symmetry of the ring. The ring is twisted and its morphology suggests a flattening ratio of 2 for the Galactic potential, which is in good agreement with the bulge flattening ratio derived from the 2MASS data.</div></front></TEI><inist><standard h6="B"><pA><fA01 i1="01" i2="1"><s0>0004-637X</s0></fA01><fA02 i1="01"><s0>ASJOAB</s0></fA02><fA03 i2="1"><s0>Astrophys. j.</s0></fA03><fA05><s2>735</s2></fA05><fA06><s2>2</s2><s3>p. 2</s3></fA06><fA08 i1="01" i2="1" l="ENG"><s1>A 100 pc ELLIPTICAL AND TWISTED RING OF COLD AND DENSE MOLECULAR CLOUDS REVEALED BY HERSCHEL AROUND THE GALACTIC CENTER</s1></fA08><fA11 i1="01" i2="1"><s1>MOLINARI (S.)</s1></fA11><fA11 i1="02" i2="1"><s1>BALLY (J.)</s1></fA11><fA11 i1="03" i2="1"><s1>NORIEGA-CRESPO (A.)</s1></fA11><fA11 i1="04" i2="1"><s1>COMPIEGNE (M.)</s1></fA11><fA11 i1="05" i2="1"><s1>BERNARD (J.

Using a simple toy model, an elliptical shape having semi-major axes of 100 and 60 pc is deduced. The major axis of this 100 pc ring is inclined by about 40° with respect to the plane of the sky and is oriented perpendicular to the major axes of the Galactic Bar. The 100 pc ring appears to trace the system of stable x<sub>2</sub> orbits predicted for the barred Galactic potential. Sgr A* is displaced with respect to the geometrical center of symmetry of the ring. The ring is twisted and its morphology suggests a flattening ratio of 2 for the Galactic potential, which is in good agreement with the bulge flattening ratio derived from the 2MASS data.</s0></fC01><fC02 i1="01" i2="3"><s0>001E03</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Nuage dense</s0><s5>26</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Dense cloud</s0><s5>26</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Nube densa</s0><s5>26</s5></fC03><fC03 i1="02" i2="3" l="FRE"><s0>Nuage moléculaire</s0><s5>27</s5></fC03><fC03 i1="02" i2="3" l="ENG"><s0>Molecular clouds</s0><s5>27</s5></fC03><fC03 i1="03" i2="3" l="FRE"><s0>Centre galactique</s0><s5>28</s5></fC03><fC03 i1="03" i2="3" l="ENG"><s0>Galactic centers</s0><s5>28</s5></fC03><fC03 i1="04" i2="3" l="FRE"><s0>Voie lactée</s0><s5>29</s5></fC03><fC03 i1="04" i2="3" l="ENG"><s0>Milky Way</s0><s5>29</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Modèle</s0><s5>30</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Models</s0><s5>30</s5></fC03><fC03 i1="05" i2="X" l="SPA"><s0>Modelo</s0><s5>30</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>Forme elliptique</s0><s5>31</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>Elliptic shape</s0><s5>31</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>Forma elíptica</s0><s5>31</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Barre galactique</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Galactic bar</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Barra galáctica</s0><s5>32</s5></fC03><fC03 i1="08" i2="3" l="FRE"><s0>Orbite</s0><s5>33</s5></fC03><fC03 i1="08" i2="3" l="ENG"><s0>Orbits</s0><s5>33</s5></fC03><fC03 i1="09" i2="3" l="FRE"><s0>Morphologie</s0><s5>34</s5></fC03><fC03 i1="09" i2="3" l="ENG"><s0>Morphology</s0><s5>34</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Aplatissement</s0><s5>35</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Flattening</s0><s5>35</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Aplanamiento</s0><s5>35</s5></fC03><fC03 i1="11" i2="3" l="FRE"><s0>Galaxies</s0><s5>36</s5></fC03><fC03 i1="11" i2="3" l="ENG"><s0>Galaxies</s0><s5>36</s5></fC03><fC03 i1="12" i2="3" l="FRE"><s0>Formation stellaire</s0><s5>37</s5></fC03><fC03 i1="12" i2="3" l="ENG"><s0>Star formation</s0><s5>37</s5></fC03><fN21><s1>220</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard></inist></record>Pour manipuler ce document sous Unix (Dilib)
