Title: New Astrometric Measurements of WDS 18234-4819 B938
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.  more » « less

    We report the measurement of the position angle and separation for the double star system HD 80460. We made use of a 0.4m telescope from Las Cumbres Observatory (LCOGT) and a DeltaRho 350 + QHY600 camera. An analysis was made with the historical data from the Washington Double Star (WDS) catalog. A search was made with SIMBAD for spectral type, parallax, and proper motion for the double star.

    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

    We report new measurements of the position angle and separation of the double star WDS 03245+5938 STI 450, based on our observations, Gaia EDR3, and historical data. We find that the position angle and separation are 209.7° and 7.68", respectively, showing slight changes from the previous values of 210° and 7.742". We also find that the distances between the two stars are far apart, suggesting that the system is an optical double, and therefore not gravitationally bound together. Furthermore, we find that the ratio of proper motion (rPM) metric of the system is distinct, indicating that the system is a chance alignment of two unrelated stars that are at different distances.

    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.

    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.
