Abstract
We present direct upper limits on continuous gravitational wave emission from the Vela pulsar using data from the Virgo detector's second science run. These upper limits have been obtained using three independent methods that assume the gravitational wave emission follows the radio timing. Two of the methods produce frequentist upper limits for an assumed known orientation of the star's spin axis and value of the wave polarization angle of, respectively, 1.9 x 10-24 and 2.2 × 10-24, with 95% confidence. The third method, under the same hypothesis, produces a Bayesian upper limit of 2.1 x 10-24, with 95% degree of belief. These limits are below the indirect spin-down limit of 3.3 x 10-24 for the Vela pulsar, defined by the energy loss rate inferred from observed decrease in Vela's spin frequency, and correspond to a limit on the star ellipticity of ˜10-3. Slightly less stringent results, but still well below the spin-down limit, are obtained assuming the star's spin axis inclination and the wave polarization angles are unknown.

These upper limits have been obtained using three independent methods that assume the gravitational wave emission follows the radio timing. Two of the methods produce frequentist upper limits for an assumed known orientation of the star's spin axis and value of the wave polarization angle of, respectively, 1.9 x 10<sup>-24</sup> and 2.2 × 10<sup>-24</sup>, with 95% confidence. The third method, under the same hypothesis, produces a Bayesian upper limit of 2.1 x 10<sup>-24</sup>, with 95% degree of belief. These limits are below the indirect spin-down limit of 3.3 x 10<sup>-24</sup> for the Vela pulsar, defined by the energy loss rate inferred from observed decrease in Vela's spin frequency, and correspond to a limit on the star ellipticity of ˜10<sup>-3</sup>. Slightly less stringent results, but still well below the spin-down limit, are obtained assuming the star's spin axis inclination and the wave polarization angles are unknown.</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>737</s2></fA05><fA06><s2>2</s2><s3>p. 1</s3></fA06><fA08 i1="01" i2="1" l="ENG"><s1>BEATING THE SPIN-DOWN LIMIT ON GRAVITATIONAL WAVE EMISSION FROM THE VELA PULSAR</s1></fA08><fA11 i1="01" i2="1"><s1>ABADIE (J.)</s1></fA11><fA11 i1="02" i2="1"><s1>ABBOTT (B.

These upper limits have been obtained using three independent methods that assume the gravitational wave emission follows the radio timing. Two of the methods produce frequentist upper limits for an assumed known orientation of the star's spin axis and value of the wave polarization angle of, respectively, 1.9 x 10<sup>-24</sup> and 2.2 × 10<sup>-24</sup>, with 95% confidence. The third method, under the same hypothesis, produces a Bayesian upper limit of 2.1 x 10<sup>-24</sup>, with 95% degree of belief. These limits are below the indirect spin-down limit of 3.3 x 10<sup>-24</sup> for the Vela pulsar, defined by the energy loss rate inferred from observed decrease in Vela's spin frequency, and correspond to a limit on the star ellipticity of ˜10<sup>-3</sup>. Slightly less stringent results, but still well below the spin-down limit, are obtained assuming the star's spin axis inclination and the wave polarization angles are unknown.</s0></fC01><fC02 i1="01" i2="3"><s0>001E03</s0></fC02><fC03 i1="01" i2="3" l="FRE"><s0>Onde gravitationnelle</s0><s5>26</s5></fC03><fC03 i1="01" i2="3" l="ENG"><s0>Gravitational waves</s0><s5>26</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Emission onde</s0><s5>27</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Wave emission</s0><s5>27</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Emisión onda</s0><s5>27</s5></fC03><fC03 i1="03" i2="3" l="FRE"><s0>Pulsar</s0><s5>28</s5></fC03><fC03 i1="03" i2="3" l="ENG"><s0>Pulsars</s0><s5>28</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Borne supérieure</s0><s5>29</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Upper bound</s0><s5>29</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Cota superior</s0><s5>29</s5></fC03><fC03 i1="05" i2="3" l="FRE"><s0>Timing</s0><s5>30</s5></fC03><fC03 i1="05" i2="3" l="ENG"><s0>Timing</s0><s5>30</s5></fC03><fC03 i1="06" i2="3" l="FRE"><s0>Etoile S</s0><s5>31</s5></fC03><fC03 i1="06" i2="3" l="ENG"><s0>S stars</s0><s5>31</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Polarisation onde</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Wave polarization</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Polarización onda</s0><s5>32</s5></fC03><fC03 i1="08" i2="3" l="FRE"><s0>Perte énergie</s0><s5>33</s5></fC03><fC03 i1="08" i2="3" l="ENG"><s0>Energy losses</s0><s5>33</s5></fC03><fC03 i1="09" i2="X" l="FRE"><s0>Taux perte</s0><s5>34</s5></fC03><fC03 i1="09" i2="X" l="ENG"><s0>Loss rate</s0><s5>34</s5></fC03><fC03 i1="09" i2="X" l="SPA"><s0>Porcentaje pérdida</s0><s5>34</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Ellipticité</s0><s5>35</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Ellipticity</s0><s5>35</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Elipticidad</s0><s5>35</s5></fC03><fC03 i1="11" i2="3" l="FRE"><s0>Etoile neutron</s0><s5>36</s5></fC03><fC03 i1="11" i2="3" l="ENG"><s0>Neutron stars</s0><s5>36</s5></fC03><fN21><s1>262</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)
