Descripción
Observations of the interstellar and circumstellar absorption components obtained with the Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) along the line of sight toward the Wolf-Rayet-luminous blue variable (LBV) system HD 5980 in the Small Magellanic Cloud are analyzed. Velocity components from C I, C I*, C II, C II*, C IV, N I, N V, O I, Mg II, Al II, Si II, Si II*, Si III, Si IV, S II, S III, Fe II, Ni II, Be I, Cl I, and CO are identified, and column densities estimated. The principal velocity systems in our data are (1) interstellar medium (ISM) components in the Galactic disk and halo (Vhel = 1.1 ± 3, 9 ± 2 km s-1); (2) ISM components in the SMC (Vhel = + 87 ± 6, + 110 ± 6, + 132 ± 6, + 158 ± 8, + 203 ± 15 km s-1); (3) SMC supernova remnant SNR 0057-7226 components (Vhel = + 312 ± 3, + 343 ± 3, + 33, +64 km s-1); (4) circumstellar (CS) velocity systems (Vhel = -1020, -840, -630, -530, -300 km s-1); and (5) a possible system at -53 ± 5 km s-1 (seen only in some of the Si II lines and marginally in Fe II) of uncertain origin. The supernova remnant SNR 0057-7226 has a systemic velocity of + 188 km s-1, suggesting that its progenitor was a member of the NGC 346 cluster. Our data allow estimates to be made of Te ∼ 40,000 K, ne ∼ 100 cm-3, N(H) ∼ (4-12) × 1018 cm-2 and a total mass between 400 and 1000 M⊙ for the supernova remnant (SNR) shell. We detect C I absorption lines primarily in the + 132 and + 158 km s-1 SMC velocity systems. As a result of the LBV-type eruptions in HD 5980, a fast-wind/slow-wind circumstellar interaction region has appeared, constituting the earliest formation stages of a windblown H II bubble surrounding this system. Variations over a timescale of 1 year in this circumstellar structure are detected.
