Title: Astrometric Measurements of Binary Star Systems WDS 19576+3454, WDS 06076+2457, and WDS 06043+2327
We used the Las Cumbres Observatory telescopes to take images of three star systems: WDS 19576+3454, WDS 06043+2327, and WDS 06076+2457, on April 3rd, April 8th, and April 4th, 2024 respectively. We analyzed their astronomical measurements using Afterglow Workbench. For WDS 19576+3454, the position angle was measured to be 265.2° ± 0.12° with an angular separation of 7.38” ± 0.022”. For WDS 06043+2327, the position angle was measured to be 298.5° ± 0.28° with an angular separation of 9.83” ± 0.036”. The new data show that both WDS 19576+3454 and WDS 06043+2327 are consistent with being physical binaries but the parallax distances from the GAIA data suggest the stars in these pairs are too far apart to be gravitationally bound. Thus we conclude these two pairs are likely optical doubles. For WDS 06076+2457, the position angle was measured to be 348.1° ± 0.10° with an angular separation of 7.96” ± 0.023”. The new data we observed, combined with available GAIA data, give evidence that WDS 06076+2457 may be a physical double.  more » « less

    We have taken astrometric measurements of three star systems: WDS 00033+5332 A 1500 AB,C, WDS 05283+0358 HJ 2266, and WDS 19557+3805 DAM 1 AB. We used the Las Cumbres Observatory telescopes to take images of these star systems, and we then analyzed them using Afterglow Workbench. For WDS 00033+5332, we found the position angle to be 81.62° ± 0.45° and an angular separation of 9.01’’ ± 0.04’’. Based on our analysis, we were not able to determine whether the WDS 00033+5332 double is physical. For WDS 05283+0358, we found the position angle to be 37.58° ± 0.15° and an angular separation of 7.29’’ ± 0.04’’. It is already known that WDS 05283+0358 is a physical double, and our new data supports this claim. For WDS 19557+3805, we found the position angle to be 234.64° ± 0.63° and an angular separation of 6.89’’ ± 0.10’’. Our new data points suggest this system is gravitationally bound

    This research delves into the analysis of the WDS 18234-4819 B 938 double-star system situated within the Telescopium constellation. Utilizing our observations, data from the Gaia Data Release 3 mission, and historical records, new measurements of the position angle and separation were acquired. The results indicate a position angle of 342.6° and a separation of 8.39", showcasing an observable increase in comparison to historical data. Furthermore, an exploration of the parallax and proper motion values suggests disparate distances from Earth and a lack of gravitational binding between the stars. Consequently, the WDS 18234-4819 B 938 double-star system is classified as an optical double. To affirm this conclusion, we advocate for future studies to monitor dynamic changes in system parameters.

    WDS 03286+2523 BRT 133, is a double-star system that has been under observation since 1896. In this study, we present new measurements of the position angle and separation of the system, utilizing data obtained from a web telescope with a Charged Couple Device (CCD) camera, Gaia EDR3, and historical records. We determined that the position angle and separation are 222.4° and 5.35", respectively, indicating a slight increase from the previous values of 222° and 5.34" measured in 2004. We also employed the parallax and the ratio of proper motion metric (rPM) values of the system to assess its binarity. This analysis showed that the system may be gravitationally bound and with a long orbital period.

    We conducted a study on two double star systems, WDS 20310-2700 (DAM 1042) and WDS 20313-2707 (SKF 2086), using the Las Cumbres Observatory (LCO) global telescope network. The goal of the study was to determine separation and position angles of the double stars and possibly determine whether the systems are gravitationally bound. Our separation and position angle for WDS 20310-2700 were 10.73 ± 0.03′′ and 1.78.9 ± 0.22°, respectively. Our separation and position angle for WDS 20313-2707 were 6.84 ± 0.11′′ and 303.9 ± 0

    The double star system WDS 22267+4433 ES 1346 AC was observed using the Las Cumbres Global Telescope Network (LCOGT) 0.4 meter telescope on October 19th, 2023. Upon observation, the position angle was 359.97° and the separation was 7.997″. This data was compared to historical data acquired from the Washington Double Star Catalog, the US Naval Observatory, and the Gaia Database. Because Gaia DR3 does not have parallax and proper motion values for the primary or secondary stars of this system, a comparison to the C component could not be made.
