since last night is available the Fall of Journal of Double Star Observations (JDSO) . In it, he published an article entitled Double-Star CCD Measurements at Palomares Road Astronomical Observatory (OACP) 2nd Series, which lists the measures of double stars that registered in 2008. Total contributions in CCD measures 146 from 125 double and multiple systems.
With this second set of measures on images taken at my observatory start a full review of Stein's catalog. This time I included 59 pairs STI, all located in Cassiopeia. Of these, three have been confirmed as only had the measure of discovery. Most other systems had two official measurements. In addition, for the entire list has been updated STI the movements of the components, data generally lacking in the WDS catalog. For this I used the new catalog UCAC3 via Aladin. The remaining steps to complete the double star list are found abandoned in nearby STI peer during observations.
I also include two new pairs provisionally called MRI and MRI 5BC 6. The first is a new STI component 216, which seems to share the proper motion component B. The second MRI 6 is a pair of stars close to STI 332 and not reported as a double date. Near the bright primary star (HD11959, HIP9321) found a faint companion to 6.24 "in the direction of 72.33 °. The visual magnitudes (V) derived in this study are 8.64 and 13.36 for the component primary and secondary respectively, after correcting the photometric data for reddening and extinction. Their photometric distances are 349 and 417 parsec and their spectra are also calculated in this study are A3V and G6V for primary and secondary school in that order. According to relevant studies, including new techniques such as probability, besides the usual criteria for characterization, MRI 6 has a high probability to be a physical system. Now we just need to wait for the USNO evaluate all data submitted for the new pairs are included or not in the WDS. I refer to the original article for more details on this job.
also publishes Francisco Rica in this issue a long article giving the results obtained by the Double Star Section of the LIADA for 2005. Again, and as usual, the English representation in these publications remain spearhead. "We will be acostrumbrando wrong? To here.
