The initial mass function based on the full-sky 20 pc census of∼ 3600 stars and brown Dwarfs
A complete accounting of nearby objects—from the highest-mass white dwarf progenitors
down to low-mass brown dwarfs—is now possible, thanks to an almost complete set of …

[HTML][HTML] Kepler main-sequence solar-like stars: surface rotation and magnetic-activity evolution
While the mission's primary goal was focused on exoplanet detection and characterization,
Kepler made and continues to make extraordinary advances in stellar physics. Stellar …

The origin of weakened magnetic braking in old solar analogs
The rotation rates of main-sequence stars slow over time as they gradually lose angular
momentum to their magnetized stellar winds. The rate of angular momentum loss depends …

A 20 second cadence view of solar-type stars and their planets with TESS: asteroseismology of solar analogs and a recharacterization of π men c
We present an analysis of the first 20 second cadence light curves obtained by the TESS
space telescope during its extended mission. We find improved precision of 20 second data …

Weakened Magnetic Braking in the Exoplanet Host Star 51 Peg
The consistently low activity level of the old solar analog 51 Peg not only facilitated the
discovery of the first hot Jupiter, but also led to the suggestion that the star could be …

Asteroseismology and Spectropolarimetry of the Exoplanet Host Star λ Serpentis
The bright star λ Ser hosts a hot Neptune with a minimum mass of 13.6 M⊕ and a 15.5 day
orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 days and …

Constraints on magnetic braking from the G8 Dwarf stars 61 UMa and τ Cet
During the first half of their main-sequence lifetimes, stars rapidly lose angular momentum to
their magnetized winds, a process known as magnetic braking. Recent observations …

TESS Asteroseismology of β Hydri: A Subgiant with a Born-again Dynamo
The solar-type subgiant β Hyi has long been studied as an old analog of the Sun. Although
the rotation period has never been measured directly, it was estimated to be near 27 days …

EXPRES. IV. Two Additional Planets Orbiting ρ Coronae Borealis Reveal Uncommon System Architecture
Thousands of exoplanet detections have been made over the last 25 years using Doppler
observations, transit photometry, direct imaging, and astrometry. Each of these methods is …
