Autor: A. Burkert, S. Gillessen, D. N. C. Lin, X. Zheng, P. Schoeller, F. Eisenhauer, R. Genzel

Publikováno v: The Astrophysical Journal, Vol 962, Iss 1, p 81 (2024)

The orbital distribution of the S-star cluster surrounding the supermassive black hole in the center of the Milky Way is analyzed. A tight dependence of the pericenter distance r _p on orbital eccentricity e _⋆ is found, $\mathrm{log}({r}_{{\rm{p}}

Young, low-mass brown dwarfs orbiting early-type stars, with low mass ratios ( q ≲ 0.01), appear to be intrinsically rare and present a formation dilemma: could a handful of these objects be the highest-mass outcomes of “planetary” formation ch

Giant exoplanets have been directly imaged over orders of magnitude of orbital separations, prompting theoretical and observational investigations of their formation pathways. In this paper, we present new VLTI/GRAVITY astrometric data of HIP 65426 b

Evidence for Large-scale, Rapid Gas Inflows in z ∼ 2 Star-forming Disks

Publikováno v: The Astrophysical Journal, Vol 957, Iss 1, p 48 (2023)

We report high-quality H α /CO imaging spectroscopy of nine massive (log median stellar mass = 10.65 M _⊙ ) disk galaxies on the star-forming main sequence (henceforth SFGs), near the peak of cosmic galaxy evolution ( z ∼ 1.1–2.5), taken with

Publikováno v: The Astrophysical Journal, Vol 956, Iss 2, p 99 (2023)

Tension remains between the observed and modeled properties of substellar objects, but objects in binary orbits, with known dynamical masses, can provide a way forward. HD 72946 B is a recently imaged brown dwarf companion to a nearby, solar-type sta

We analyze H α or CO rotation curves extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy star formation ( z ∼ 0.6–2.5), more than doubling the previous sample
