Combined fit results for K2-79 b. Transit fit to the light curve data from K2 long cadence (first row left), TESS long cadence (first row centre), and CHEOPS (first row right). The cadence (29.4 min for K2 long cadence, 120 s for TESS long cadence, and 60 s for CHEOPS) fluxes are plotted in grey, the fluxes binned every 30 min are over-plotted in black, and the fitted transit is shown by the red solid line. The RV fit to the HARPS-N & HIRES RVs is shown in the second row for K2-79 b. Coloured circular points show the phase folded RVs, grey points show these same values in subsequent phases, and the black line shows the best fit Keplerian model. The third row shows the RVs over the full ∼ 9 yr baseline, illustrating the absence of any significant long term trend. -- astro-ph.EP

Disk physical structure from our three parametric models (Models 1 to 3 from top to bottom, see Tables 1 and 2). The 2D gas temperature (left) and total H density (right) are shown as colors, with iso-curves in white. The dashed red line corresponds to AV = 1 mag (as measured from the top). -- astro-ph.EP

(A) The model of EnINpro is colored by different domains with arrows representing β strands. The model highlights a β-solenoid fold (gray, purple) adjacent to the disulfide capping motif (orange). (B) Cross section through the central domain region. Residues are identified by their one-letter codes. Boxes indicated the location of the characteristic TQT, SLT, and YGS motifs. (C) Cross section of the central domain’s capping structure, where adjacent cysteine residues can form disulfide bonds that likely stabilize the β-solenoid fold. -- Science Advances via PubMed

A Scanning Electron Microscope (SEM) micrograph of a SiGe transistor for use on ocean worlds. This SiGe IC is built from large numbers of micron-sized (10^-6 m) SiGe transistors to enable electronic functionalities such as communications, sensing, and control. The entire SiGe IC is 5x5 mm^2 and the X-band (8-12 GHz) SiGe RF communications link is shown in the lower right. Image credit: John D. Cressler, Georgia Tech

Comparison of various tracers of dust, gas, and extinction toward the CygX region. Cyan contours in all images indicate H2O ice peak optical depths of 0.25, derived from the H2O ice map smoothed with a Gaussian kernel of σ ∼ 31′′ (5 pixels). (a) 2MASS NICEST AJ extinction, with a resolution of 3′ . (b) FCRAO 13CO (1–0) Moment 0 map (beamsize 45′′ FWHM) integrated over −10 to +20 km s−1 , corresponding to the ensemble of star-forming molecular clouds directly associated with the Cyg OB2 cluster (N. Schneider et al. 2006). (c) Herschel-derived NH2 column density. (d) Herschel-derived dust temperature, Td. Both Herschel images are at a resolution of 36.4′′ -- astro-ph.GA

Schematic of the two-channel picture. As the atmosphere expands and rarefies, a fraction of particles decouples from the collisional flow and streams outward ballistically. The collisional channel can remain Parker-like and transonic, while the growing collisionless channel can cause the flux-weighted bulk speed to peak at a quasi-sonic point and decrease at larger radii. -- astro-ph.EP
