Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs

TL;DR: In this paper , the authors report the galactocentric distances of different outflow components for both a sample and an individual quasar and find that the outflow distance increases with velocity, with a typical value from several parsecs to more than one hundred parsec, providing direct evidence for an acceleration happening at a scale of the order of 10 parsec.

Mutual Inclination of Ultra-short-period Planets with Time-varying Stellar J 2 Moments
TL;DR: In this article , the authors investigate how the final mutual inclination varies under the effect of a decreasing J 2 moment, and they find that different initial parameters (e.g., the magnitude of J 2 and planetary inclinations) will contribute to different final mutual inclinations, providing a constraint on the formation mechanisms of USP planets.

Nature and Origins of Rich Complexes of C iv Associated Absorption Lines
TL;DR: This paper studied five quasars at redshifts 3.1 to 4.4 with AAL complexes containing from 7 to 18 CIV 1548, 1551 systems in high-resolution spectra.

Constraining Young Hot Jupiter Occurrence Rate in Stellar Associations Using 2-min Cadence TESS Data
Yuanqing Fang,Bo Ma,Chen Chen +2 more
TL;DR: In this paper , the authors conduct a systematic search for young planets from young open clusters and associations using the 2-min cadence TESS survey data and obtain TESS light curves for a total of 1075 young stars, which are selected with the aid of Gaia data.
Absorption-line Environments of High-redshift BOSS Quasars
TL;DR: In this paper, the authors examined the correlation of narrow absorption lines (NALs) at positive and negative velocity shifts to other quasar properties, such as their broad absorption-line (BAL) outflows and radio-loudness, using spectral data from SDSS-BOSS DR12.
