cds-question@unistra.frmultiple-starsphotometryWe present high-angular-resolution optical I-band imaging of 451 late K to mid-M nearby stars. These observations have been performed with Astralux and FastCam using the lucky imaging technique. We found 70 companions with separations between 0.1 and 3.5-arcsec, out of which 28 are new discoveries. We derive a total binary fraction of 20.3^+6.9^_-5.2_ per cent. Follow-up observations have been carried out for 16 of these new binaries and all of them were confirmed as physically associated systems. Parallaxes are available for 70 per cent of the binary sample, providing reliable estimates of physical separations. We have measured separations and position angles as an initial stage for a systematic follow-up aimed to determine orbital parameters.2013MNRAS.429..859Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/429/859CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/70 : Nearby Stars, Preliminary 3rd Version (Gliese+ 1991)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/429/859https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/429/859http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/429/859https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/429/859https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/429/859http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/429/859GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/429/859/table1 (Objects observed in our survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/429/859/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/429/859/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/429/859/table1?GETtext/xml+votable180.050000true7.1645-6.66336110.0055555555555555566/131 307 648 654 691 696 725 1212 1845 1875 1911 2282 2747 2911 3015 3658 3715 3751 3768 3791 4104 4127 4144 4250 4297 4366 4493 4553 4555 4595 4689 4693 4708 4775 4805 4845 5000 5009 5061 5092 5154 5318 5387 5420 5474 5488 5514 5534 5622 5676 5733 5849 5910 5998 6045 6073 6242 6277 6281 6346 6384 6410 6419 6433 6662 6736 6752 6879 6890 6924 6967 6974 7003 7046 7129 7132 7205 7262 7465 7471 7512 7552 7611 7736 7745 7772 7775 7837 8023 8032 8123 8440 8562 8592 8683 8843 8887 8894 9178 9188 9384 9399 9407 9415 9436 9578 9585 9621 9629 9681 9696 9746 9750 9775 9811 10027 10090 10146 10149 10156 10169 10225 10270 10274 10303 10388 10448 10457 10464-10465 10467 10476 10626 10669 10683 10721 10735 10771 10818 10912 10915 10928 10983 11029 11034 11126 11177 11197 11255 11276 11496 11565 11636 11919 11962 12128 12359 12454 12652 12679 12795 12865 12889 12915 13065 13155 13262 13427 13512 13669 13788 13929 13931 13960 14192 14234 14277 14314 14377 14395 14410 14419 14456-14457 14481 14515 14583 14666 14709 14772 14842 14850 14924 14982 14993 14998 15031 15052 15431 15442 15530 15548 15602 15861 15885 15960 16006 16137 16201 17124 17271 17358 17455 17486 17511 18195 18201 18325 18440 18496 18538 18553 18588 18666 18758 18785 18789 18802 18856 18913 18929 18959 19050 19064 19068 19133 19157 19163 19187 19224 19243 19257 19306 19323 19361 19515-19516 19559 19815 19836 19958 20071 20074 20100 20109 20311 20324 20352 20404 20867 20896 21133 21151 21392 21399 21646 21747 21777 21946 22040 22140 22277 22289 22309 22518 22636 22807 22873 22904 22964 23000 23010 23056 23388 23534 23545 23718 23741 23787 23858 23867 23997 24093 24103 24227 24297 24350 24356 24369 24519 25198 25283 25426 25516 25792 25849 25989 26071 26216 26281 26288 26327 26495 26538 26555 26560 26563 26583 26614 26708 26714 26772 26916 27201 27260 27289 27335 27392 27419 27459 27462 27484 27509 27519 27704 27730-27731 27734 27772 27799 27810 27849 27912 27973 28018 28042 28087 28207 28223 28283 28341 28343 28478 28494 28548 28646 29143 29170 29566 29595 29665 29684 29738 30035 30195 30345 30350 30407 30429 30464 30490 30505 30525 30529 30626 30638 30735 30771 30833 30956 30978 31001 31010 31013-31014 31019 31035 31191 31229 31606 31613 31630 31758 31787 31811 31956 32033 32052 32055 32115 32161 32164 32259 32319 32335 32380 32458 32491 32500 32547 32588 32652 32678 32730 36125 36511 39242 39585 39792 40505 40679 40688 40760 40795 40820 40893 44793 44921 44937 44970 48633 48926 48958 48964 48985 48999 49015 49048 49101 49113 49125https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/429/859?format=asciiOpticaldefaultJ/MNRAS/429/859/table1Objects observed in our surveyrecnoRecord number assigned by the VizieR team.
