Abstract
We have detected asymmetry in the symbiotic star CH Cyg through the measurement of precision closure phase with the Integrated Optics Near-Infrared Camera (IONIC) beam combiner, at the infrared optical telescope array interferometer. The position of the asymmetry changes with time and is correlated with the phase of the 2.1-year period found in the radial velocity measurements for this star. We can model the time-dependent asymmetry either as the orbit of a low-mass companion around the M giant or as an asymmetric, 20 per cent change in brightness across the M giant. We do not detect a change in the size of the star during a 3-year monitoring period neither with respect to time nor with respect to wavelength. We find a spherical dust shell with an emission size of 2.2 ± 0.1 D* full width at half-maximum around the M giant star. The star to dust flux ratio is estimated to be 11.63 ± 0.3. While the most likely explanation for the 20 per cent change in brightness is non-radial pulsation, we argue that a low-mass companion in close orbit could be the physical cause of the pulsation. The combined effect of pulsation and low-mass companion could explain the behaviour revealed by the radial velocity curves and the time-dependent asymmetry detected in the closure-phase data. If CH Cyg is a typical long secondary period variable then these variations could be explained by the effect of an orbiting low-mass companion on the primary star.

The position of the asymmetry changes with time and is correlated with the phase of the 2.1-year period found in the radial velocity measurements for this star. We can model the time-dependent asymmetry either as the orbit of a low-mass companion around the M giant or as an asymmetric, 20 per cent change in brightness across the M giant. We do not detect a change in the size of the star during a 3-year monitoring period neither with respect to time nor with respect to wavelength. We find a spherical dust shell with an emission size of 2.2 ± 0.1 D<sub>*</sub> full width at half-maximum around the M giant star. The star to dust flux ratio is estimated to be 11.63 ± 0.3. While the most likely explanation for the 20 per cent change in brightness is non-radial pulsation, we argue that a low-mass companion in close orbit could be the physical cause of the pulsation. The combined effect of pulsation and low-mass companion could explain the behaviour revealed by the radial velocity curves and the time-dependent asymmetry detected in the closure-phase data. If CH Cyg is a typical long secondary period variable then these variations could be explained by the effect of an orbiting low-mass companion on the primary star.</s0></fC01><fC02 i1="01" i2="3"><s0>001E03</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Pulsation non radiale</s0><s5>26</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Non radial pulsation</s0><s5>26</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Pulsación no radial</s0><s5>26</s5></fC03><fC03 i1="02" i2="3" l="FRE"><s0>Etoile symbiotique</s0><s5>27</s5></fC03><fC03 i1="02" i2="3" l="ENG"><s0>Symbiotic stars</s0><s5>27</s5></fC03><fC03 i1="03" i2="3" l="FRE"><s0>Asymétrie</s0><s5>28</s5></fC03><fC03 i1="03" i2="3" l="ENG"><s0>Asymmetry</s0><s5>28</s5></fC03><fC03 i1="04" i2="3" l="FRE"><s0>Position</s0><s5>29</s5></fC03><fC03 i1="04" i2="3" l="ENG"><s0>Positions</s0><s5>29</s5></fC03><fC03 i1="05" i2="3" l="FRE"><s0>Vitesse radiale</s0><s5>30</s5></fC03><fC03 i1="05" i2="3" l="ENG"><s0>Radial velocity</s0><s5>30</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>Modèle</s0><s5>31</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>Models</s0><s5>31</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>Modelo</s0><s5>31</s5></fC03><fC03 i1="07" i2="3" l="FRE"><s0>Orbite</s0><s5>32</s5></fC03><fC03 i1="07" i2="3" l="ENG"><s0>Orbits</s0><s5>32</s5></fC03><fC03 i1="08" i2="X" l="FRE"><s0>Enveloppe sphérique</s0><s5>33</s5></fC03><fC03 i1="08" i2="X" l="ENG"><s0>Spherical envelope</s0><s5>33</s5></fC03><fC03 i1="08" i2="X" l="SPA"><s0>Envoltura esférica</s0><s5>33</s5></fC03><fC03 i1="09" i2="X" l="FRE"><s0>Enveloppe poussière</s0><s5>34</s5></fC03><fC03 i1="09" i2="X" l="ENG"><s0>Dust shell</s0><s5>34</s5></fC03><fC03 i1="09" i2="X" l="SPA"><s0>Envoltura polvo</s0><s5>34</s5></fC03><fC03 i1="10" i2="3" l="FRE"><s0>Etoile M</s0><s5>35</s5></fC03><fC03 i1="10" i2="3" l="ENG"><s0>M stars</s0><s5>35</s5></fC03><fC03 i1="11" i2="3" l="FRE"><s0>Etoile géante</s0><s5>36</s5></fC03><fC03 i1="11" i2="3" l="ENG"><s0>Giant stars</s0><s5>36</s5></fC03><fN21><s1>222</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard></inist><affiliations><list><country><li>Australie</li><li>France</li><li>Royaume-Uni</li><li>États-Unis</li></country><region><li>Massachusetts</li><li>Nouvelle-Galles du Sud</li></region><settlement><li>Amherst (Massachusetts)</li><li>Sydney</li></settlement><orgName><li>Université du Massachusetts</li></orgName></list><tree><country name="Royaume-Uni"><noRegion><name sortKey="Pedretti, E" sort="Pedretti, E" uniqKey="Pedretti E" first="E." last="Pedretti">E.
