Descripción
The paper presents detailed high-spatial-resolution spectroscopy of seven WR ring nebulae, observed at several telescopes in both hemispheres. These are Anon (MR 26), Anon (MR 100), G 2.4 + 1.4, L 69.8 + 1.74, NGC 3199, RCW 104, and S 308. Using line diagnostic diagrams, it is found that photoionization is the main excitation source in the sample. Physical conditions and chemical abundances are derived for as many of the observed slit positions as possible in each nebula.

    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

    An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: I. The properties of the 870 micron counterparts
    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
