cds-question@unistra.frexoplanetshigh-velocity-starsIdentifying which systems are more likely to host an imageable planet can play an important role in the construction of an optimized target list for future direct imaging missions, such as the planned Coronagraph Instrument (CGI) technology demonstration for the Nancy Grace Roman Space Telescope. For single-planet systems, the presence of an already detected exoplanet can severely restrict the target's stable region and should therefore be considered when searching for unknown companions. To do so, we first analyze the performance and robustness of several two-planet stability criteria by comparing them with long-term numerical simulations. We then derive the necessary formulation for the computation of (a, R) analytic stability maps, which can be used in conjunction with depth-of-search grids in order to define the stable-imageable region of a system. The dynamically stable completeness (i.e., the expected number of imageable and stable planets) can then be calculated via convolution with the selected occurrence grid, obtaining a metric that can be directly compared for imaging prioritization. Applying this procedure to all the currently known single-planet systems within a distance of 50pc, we construct a ranked target list based on the CGI's predicted performance and SAG13 occurrence rates. Finally, we evaluate the importance of considering the radial velocity data from past Doppler surveys in order to rule out entire regions of our parameter space where, if a planet existed, it would have certainly been detected by previous RV observations.2020AJ....160...84Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/84CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/834/17 : Mass & radius of planets, moons, low mass stars (Chen+, 2017)J/A+A/605/A72 : Planetary systems AMD-stability (Laskar+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/160/84https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/160/84http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/160/84https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/160/84https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/160/84http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/160/84GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/160/84/tablea1 (Dynamically stable depth-of-search and completeness values)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/160/84/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/160/84/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/160/84/tablea1?GETtext/xml+votable180.050000true217.4289422-62.67949030.0055555555555555566/311 320 341 679 725 737 918 1544 2110 2254 2497 2515 3350 3715 3932 4104 4444 4528 4574 4651 4881 5309 5420 5718 5849 6219 6760 6791 6831 8384 8843 9662 9753 9843 10146 10149 10225 10278 11015 11473 11636 11671 11699 11732 11910 12082 12146 12465 12502 12592 12899 14525 14682 15174 15273 15345 15635 16213 16652 16823 16995 17341 17641 17730 18614 18666 18688 18747 19131 19619 19782 19912 20145 20886 21076 21580 21742 21956 22036 22252 22590 22654 23201 23363 23540 23583 23646 24019 24227 24312 24530 24713 24816 24831 25055 25140 25466 25593 25939 25989 26142 26242 26521 26575 26901 26972 26997 27088 27616 27750 27975 28040 28258 28548 28767 28865 29291 29513 29520 29852 30009 30015 30505 31216 32335 32491 32509 32575 32930 33042 33243 33430 33456 33630 33717 34026 34301 34905 35079 35121 35268 35442 35532 35786 35814 35907 35928 35954 35968 36078 36195 36697 37018 37477 37954-37955 38238 38330 38414 38461 38545 38728 38744 38807 38937 38998 39185 39257 39364 40143 40220 40985 41058 41446 41515 41591 41607 41724 41905 41912 42290 42333 42386 42510 42760 43012 43228 43336 43374 43639 43813 43818 43911 44223 44228 44379 44398 45143 45258 45364 46112 46244 46297 46306 46682 46800 46967 47550 47740 47780 48105 48500 48530https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/160/84?format=asciidefaultJ/AJ/160/84/tablea1Dynamically stable depth-of-search and completeness valuesNameTarget name (1)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
