cds-question@unistra.frmultiple-starsinfrared-photometryvisible-astronomyphotometryinterferometryWe present our first results of multiband Speckle Holography of components of visual double stars. The observations were performed during 2019-April at the 2.1m telescope at the Observatorio Astronomico Nacional at Sierra de San Pedro Martir (Mexico). We have observed 190 double stars with separation between 3" and 5". The position angle, separation and magnitude difference in three broadband optical filters (VRI) for these systems are provided. For 15 systems we found different interesting features, we have identified a close component for 9 of those systems; 5 of them are newly discovered. In the remaining 6 systems, although unresolved, we found elongations that we have been able to derive astrometric parameters if proven to be a (newly discovered) close component. This corresponds to about 8% of the sample presenting a certain feature in one of the components and about 5% of the sample having a confirmed close component.2020AJ....160....9Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/9CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)I/237 : The Washington Visual Double Star Catalog, 1996.0 (Worley+,1996)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/AJ/131/1000 : Double star speckle measures (Horch+, 2006)J/AJ/139/205 : 2007-2008 WIYN speckle observations of binaries (Horch+, 2010)J/other/RMxAA/47.211 : Speckle interferometry at OAN.
