Observations with DSSI. XI. APO binaries measures
Listed in IVOA Registry (Virtual Observatory)
The Differential Speckle Survey Instrument (DSSI) was relocated to the Astrophysical Research Consortium 3.5m telescope at Apache Point Observatory (APO) in early 2022.
Description
Here we present results from the first year of observations along with an updated instrument description for DSSI at APO, including a detailed description of a new internal slit mask assembly used to measure the instrument plate scale from first principles.
Astrometric precision for DSSI at APO during this time was measured to be 2.06{+/-}0.11mas, with a photometric precision of 0.14{+/-}0.04mag. Results of 40 resolved binary systems are reported, including two that were previously unknown to be binaries: HIP7535 and HIP9603. We also present updated orbital fits for two systems: HIP93903 and HIP100714.

Finally, we report updated or confirmed dispositions for five Kepler Objects of Interest (KOIs) that were previously explored in Colton et al., using speckle imaging to discern common proper motions pairs from line of sight companions: KOI-270, KOI-959, KOI-1613, KOI-1962, and KOI-3214AB.
