----------------------------------- romh 29 Iun 2025 14:12 ----------------------------------- Alaltaieri am verificat blogul lui David, apoi prin linkuri externe am ajuns la AB Sonka, un nume pe care nu l-am auzit demult. Intr-una din postari se vorbea despre asteroizi cu luminozitate mica, asa ca m-am gandit sa caut in catalogul gaia stele cu luminozitate mica si paralaxa sa zicem peste 100 mas.... Interogarea propriu zisa este urmatoarea SELECT source_id, ra, dec, pmra, pmdec, parallax, phot_g_mean_mag FROM gaiadr3.gaia_source WHERE parallax > 100 AND phot_g_mean_mag > 7 AND dec > 0 ORDER BY phot_g_mean_mag ASC, parallax DESC Am primit 132 surse luminoase, daca luam si emisfera sudica numarul era dublu. Stelele cu miscare proprie mare (HPM) apareau cu nuante duble albastre/galbene in DSS2... atasez o poza mai jos, dar nu stiu sigur daca e ceva caracteristic anume acestor stele sau artefacte de procesare. Apoi nu am facut decat sa dau click de dreapta si sa verific cu simbad pe care il ridica in slavi nobody. Vasta majoritate a surselor luminoase sunt High Proper Motion Star sau HPM. Cateva sunt "Low Mass Star" orice ar insemna asta. Apoi pitice albe si in sf pitice brune. Sunt interesante acele stele care par sa faca parte din sisteme stelare duble cu planete extrasolare... source_id Descriere TYPE More 1022456104850892928 HD79211 HPM Ursa Major 385334230892516480

compari id-ul gaia la toate stelele returnate...
