Descripción
Maps in the CO (J = 2-1) line of the southern H II region complexes Carina Nebula and G333.6-0.2/RCW 106 are presented and discussed. Results for the Carina Nebula indicate a complicated spatial structure; an extended molecular cloud appears to be wrapped partly around the brightest parts of the H II region (Car I and Car II). The situation in Carina is consistent with a model for sequential star formation proposed by Elmergreen and Lada (1977). At the positions of the other sources observed, a giant molecular complex, at least 75 pc long and 20 pc wide, is found. The complex consists of at least four large clouds and coincides accurately with a distinct minimum in the H I distribution.

    Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants
    Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase in which the convective envelope deepens, mixing previously interior-processed material and bringing it to the surface. Yet, very few have been seismically characterized with Kepler because their oscillation frequencies are close to the 30 minute

    Context. Over the past 15 years, studies of quasars in the far-infrared (FIR) have reported host luminosities ranging from 10 12 to 10 14 L ⊙. These luminosities, often derived from Herschel/SPIRE photometry, suggest star formation rates (SFRs) of up to several thousand M ⊙ yr ‑1, positioning them among the most luminous starburst galaxies in the

    Transit timing variations in HIP 41378: CHEOPS and TESS confirm a non-transiting sixth planet in the system
    In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are in or near mean-motion resonances (MMRs), making them more easily detectable. In cases where both TTVs and radial velocity (RV) measurements are available, combined
