Radial velocity data reveal a 310-day orbital period in NaSt1 with opposing phases in two groups of emission lines, supporting its nature as a post-mass-transfer massive binary system.
New infrared spectra show reduced water ice and unusually strong aliphatic hydrocarbon absorption towards W44, attributed to shock and cosmic-ray processing in the associated molecular cloud.
Random Forest regression on combined optical plus mid-infrared colors yields NMAD of 0.0188, R-squared of 0.9561, and 0.294 percent outliers for photometric redshifts in 23,797 Seyfert II galaxies selected from SDSS and WISE.
In Tombaugh 2, 32% of blue straggler stars show ultraviolet excess from hot companions consistent with recent binary mass transfer, supporting this channel over mergers in a low-density cluster.
