cds-question@unistra.frmilky-way-galaxyhalo-starsstellar-distanceradial-velocityvisible-astronomyStream stars removed by tides from their progenitor satellite galaxy or globular cluster act as a group of test particles on neighbouring orbits, probing the gravitational field of the Milky Way. While constraints from individual streams have been shown to be susceptible to biases, combining several streams from orbits with various distances reduces these biases. We fit a common gravitational potential to multiple stellar streams simultaneously by maximizing the clustering of the stream stars in action space. We apply this technique to members of the GD-1, Palomar 5 (Pal 5), Orphan, and Helmi streams, exploiting both the individual and combined data sets. We describe the Galactic potential with a Stackel model, and vary up to five parameters simultaneously. We find that we can only constrain the enclosed mass, and that the strongest constraints come from the GD-1, Pal 5, and Orphan streams whose combined data set yields M(<20kpc)=2.96^+0.25^_-0.26_x10^11^M_{sun}_. When including the Helmi stream in the data set, the mass uncertainty increases to M(<20kpc)=3.12^+3.21^_-0.46_x10^11^M_{sun}_.2021MNRAS.502.4170Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/502/4170CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/ApJ/842/120 : Large spectrosc. survey of Palomar 5 stellar streamJ/MNRAS/485/4726 : An all-sky view of the Orphan Stream (Koposov+, 2019)J/other/RAA/17.62 : Candidate members of 4 stellar streams (Li+, 2017)J/AJ/158/223 : RR Lyrae members of the Pal 5 stellar streamJ/ApJ/697/207 : Cold stellar stream orbit fit (Willett+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/502/4170https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/502/4170http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/502/4170https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/502/4170https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/502/4170http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/502/4170GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/502/4170/streams (Stream catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/502/4170/streams?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/502/4170/streams?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/502/4170/streams?GETtext/xml+votable180.050000true178.5169654.58651030.0055555555555555565/1420 1447 6/812 916 949 1058 1185 1523 1971 2114 2121 2131 2259 2335 2379 2404 2576 2599 2943 3014 4015 4063 4116-4117 4121 4248-4249 4255 4273 4292 4298 4331 4393 4432-4434 4441 4443-4444 4468 4470 4473 4479 4538-4539 4549 4561 4563-4564 4567 4573 4624 4676 4695 4733 4802 4804 4903 4933 4941 4946-4947 4950-4951 4953 4957 5001 5055 5081 5118 5124 5131 5136 5144 5162-5163 5200 5228 5248-5250 5252 5256 5259 5289 5292 5295 5524 5634 5639-5641 5644 5648 5650 5659-5661 5686 5688 5690 5692 5694 5703-5704 5709 5715 5718 5736 5755 5770 5776 5781 5784 5787 5821 5823 5825-5826 5836 5858-5859 5866-5867 5890-5891 5894-5896 5906-5907 5910 5912 5916 5954 5964-5965 5971-5972 5974-5976 6013 6036 6170 6232 6238 6243 6247 6341 6354 6405 6460 6565 6758 7187 7234 7261 7267 8121 8246 8357 8379 8458 8609 8838 8841 8917 8942 8954 8961 8980 8983 9065 9083 9087 9140 9154 9358 9420 9444 9602 9673 9771 9773 9781 9877 10058 10061 10271 10332 10337 10368 10383 10409 10423 10438 10458-10459 10484 10490 10513 10525 10647 10661 10666-10667 10774-10775 10817 10853 10864 10894 10901 10964 10977 11013 11198 11304 11380-11381 11411 11438 11521 11652 11732 11787 11803 11997 12366 12376 12411 12578 12684 13363 13481 13568 13612 13697 13921 14750 14857 14972 15019 15052 15057 15232 16115 16273 16500 16659 16736 17166 17174 17323 17505 17654 17746 17876 17894 17902 18005 18105 18113 18164 18208 18224-18225 18311 18313 18316 18370 18382 18425 18456 18504 18547 18848 18886 18975 19083 19198 19257 19293 19300 19408 19525 19562 19628 19638 19732 19773 20009 20169 20188 20358 20360 20389 20438 20479 20618 20623 20990 21844 21859 21926 22199 22493 22679 22839 22978 22998 23065 23220 23236 23330 23490 23529 23579 23763 23876 23931 23933 23986 24407 24571 24616 24715 24751 24870 25017 25113 25119 25194 25288-25289 25291 25294 25312-25313 25316 25319 25336 25670 25849 25851 25904 25932 26045 26062 26189 26244 26265 26275 26279 26293 26318 26329 26377 26382 26408 26419 26432 26477 26534 26551 26567 26589 26595 26695 26740 26890 26989 27000 27028 27036 27044-27045 27047 27052-27053 27062 27087 27092 27304 27326 27446 27454 27496 27538 27543 27584 27618 27630 27634 27641-27642 27659 27668 27694 27729 27860 27873 27891 27907 27910-27911 27920 27939 27952 27963 27980 27989 28067 28133 28138 28149 28180-28181 28216 28327 28338 28400 28429 28478 28553 28595 28618 30675 31392-31394 31396 31398-31399 31409-31414 31422 31427 31439 31450-31451 31453 31456-31457 31460 31547 31551 31587 31619 31733 31938 32219 32409 32429 32495 33178 33252 33344 33671 33785 33878 34039 35019 35268 35279 35440 35518 35754 35873 35875 36009 36094 36398 36631 36714 36859 37517 37540 37632 37948 38087 38128 38226 38233 38265 38288 38316 38700 39307 39451 39493 39529 39940 40207 40665 40882 41256 41272 41285 41345 41502 41574 41900 41974 42036 42112 42120 42994 43659 43846 44208 44926 44979 45024 45028 45041 45044-45045 45168 45389 45425 46082 46115 46133 46598 47007 47044 47085 47575 47620 48724 48791 49092 49129https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/502/4170?format=asciiOpticaldefaultJ/MNRAS/502/4170/streamsStream cataloguerecnoRecord number assigned by the VizieR team.
