Random distraction from, everything else…. Is anyone dyeing yarn to match the WNBA teams? (If anyone has Valkyries inspired colorways, please let me know!) #indieyarndyers #knitting

More Kepler light curves 🤩🤩🤩
scottwfleming.bsky.social Dr. Scott W. Fleming @scottwfleming.bsky.social · Nov 1
Really cool, new HLSP: KBONUS-BKG, PSF photometry light curves from the prime Kepler mission (Martinez-Palomera et al. 2023). They extracted 606,900 sources up to G mag < 19, including 406,548 new light curves from background sources in target pixels. archive.stsci.edu/hlsp/kbonus-... 🔭
Four-panel color-magnitude plots, upper-left shows Kepler Targets, upper-right shows KBonus Background Only targets, bottom-left shows All KBonus sources, bottom-right shows the density of background / target. The bottom-right diagram shows that many of the background sources tend to be redder in BP-RP and fainter compared to Kepler targets. In all plots the y-axis ranges from 15 to -5 in G magnitude, and the x-axis ranges from -1 to 4 in BP-RP color. A two-panel plot showing the 21 Kepler CCDs shown in R. A. versus Declination space on the sky. The top panel is a density plot color-coded to show the location of Kepler targets. The bottom panel is a density plot color-coded to show the bacground sources from KBonus, the majority of which are at lower declinations. The lightest color (yellow) encoding represents 110 sources while the darkest color (dark blue) represents 0 sources.

Whoa! That’s cool!!! 🤩🤩🤩

NASA wrote up the latest result out of our Scaling K2 collaboration!

Our analysis, led by Jon Zink, showed that stars that travel high above the Galactic plane have fewer small, short-period planets than those that stay near the same.

This says something new about the Galactic census of planets!!
Discovery Alert: On Our Galaxy's Outskirts, a Poverty of Planets
Stars farther from the center of our galaxy possess fewer of the most common types of planets, a recent study shows.
