Slow solar wind sources. High-resolution observations with a quadrature view
DOI: 10.1051/0004-6361/202345983 Bibcode: 2023A&A...673A..74B

Context. The origin of the slow solar wind is still an open issue. One possibility that has been suggested is that upflows at the edge of an active region can contribute to the slow solar wind.
Aims: We aim to explain how the plasma upflows are generated, which mechanisms are responsible for them, and what the upflow region topology looks lik…

Kepler's last planet discoveries: two new planets and one single-transit candidate from K2 campaign 19
DOI: 10.1093/mnras/stad1049 Bibcode: 2023MNRAS.523..474I

Vanderburg, Andrew; Bieryla, Allyson; Latham, David W. +9 more

The Kepler space telescope was responsible for the discovery of over 2700 confirmed exoplanets, more than half of the total number of exoplanets known today. These discoveries took place during both Kepler's primary mission, when it spent 4 yr staring at the same part of the sky, and its extended K2 mission, when a mechanical failure forced it to …

Martian Atmospheric Aerosols Composition and Distribution Retrievals During the First Martian Year of NOMAD/TGO Solar Occultation Measurements: 2. Extended Results, End of MY 34 and First Half of MY 35

This is the second part of Stolzenbach et al. (2023, https://doi.org/10.1029/2022JE007276), named hereafter Paper I, extends the period to the end of MY 34 and the first half of MY 35. This encompasses the end phase of the MY 34 Global Dust Storm (GDS), the MY 34 C-Storm, the Aphelion Cloud Belt (…

The DIVING3D Survey - Deep IFS View of Nuclei of Galaxies - III. Analysis of the nuclear region of the early-type galaxies of the sample
DOI: 10.1093/mnras/stad1130 Bibcode: 2023MNRAS.522.2207R

Ricci, T. V.; Steiner, J. E.; Menezes, R. B. +2 more

We analysed the nuclear region of all 56 early-type galaxies from the DIVING3D Project, which is a statistically complete sample of objects that contains all 170 galaxies in the Southern Hemisphere with B < 12.0 mag and galactic latitude |b| < 15°. Observations were performed with the Integral Field Unit of the Gemini Multi-Object…

Revealing the ionising star of evolved planetary nebulae
DOI: 10.1051/0004-6361/202346401 Bibcode: 2023A&A...676A...1W

Werner, K.; Firpo, V.; Weidmann, W. A. +2 more

Context. Planetary nebulae represent a late stage of the evolution of stars of ordinary mass. The nucleus of a planetary nebula, a stellar remnant, is a faint star for which it is usually difficult to gather spectroscopic data. The spectral types of these stars cover a wide range, mainly separated into two large groups, those rich in hydrogen and …

The Interstellar Medium Scaling Relations Using Inner H I and an Application of Estimating Dust Mass
DOI: 10.3847/1538-4357/accbc0 Bibcode: 2023ApJ...950...84L

Lin, Zesen; Kong, Xu; Li, Fujia +4 more

We select a disk-like galaxy sample with observations of the H I, H2, and dust from the Herschel Reference Survey, and derive inner H I masses within the optical radius. We find that the inner gas-to-dust ratio is almost independent of gas-phase metallicity, and confirm that the inner gas mass (H I+H2) shows a tighter relatio…

Young Stellar Object Candidates in IC 417
DOI: 10.3847/1538-3881/ace32f Bibcode: 2023AJ....166...87R

Rebull, L. M.; Hall, G.; Anderson, R. L. +12 more

IC 417 is in the Galactic plane, and likely part of the Aur OB2 association; it is ~2 kpc away. Stock 8 is one of the densest cluster constituents; off of it to the east, there is a "nebulous stream" (NS) that is dramatic in the infrared (IR). We have assembled a list of literature-identified young stellar objects (YSOs), new candidate YSOs from t…

Searching for C II Emission from the First Sample of z ∼ 6 O I Absorption-associated Galaxies with the Atacama Large Millimeter/submillimeter Array
DOI: 10.3847/1538-4357/ad00b8 Bibcode: 2023ApJ...958...16W

Hennawi, Joseph F.; Fan, Xiaohui; Prochaska, J. Xavier +13 more

We report the first statistical analyses of [C II] and dust continuum observations in six strong O I absorber fields at the end of the reionization epoch obtained by the Atacama Large Millimeter/submillimeter Array (ALMA). Combined with one [C II] emitter reported in Wu et al., we detect one O I-associated [C II] emitter in six fields. At redshift…

Atomic oxygen abundance toward Sagittarius B2
DOI: 10.1051/0004-6361/202245481 Bibcode: 2023A&A...669L..15L

Wiesemeyer, Helmut; Güsten, Rolf; Seo, Youngmin +4 more

A substantial fraction of oxygen in diffuse clouds is unaccounted for by observations and is postulated to be in an unknown refractory form, referred to as unidentified depleted oxygen (UDO), which, depending on the local gas density, may contribute up to 50% of the total oxygen content. Previous Infrared Space Observatory (ISO) observations sugge…

We report eight new exoplanet candidates discovered at the Special Astrophysical Observatory of the Russian Academy of Sciences using the transit technique. Photometric observations were performed with a 50-cm robotic telescope during the second half of 2020. Transits with depths of $$\Delta m=0\ov…
