First Resolution of a Main Sequence G-Star Astrosphere Using Chandra
C. M. Lisse, S. J. Wolk, B. Snios +24
We report resolution of a halo of X-ray line emission surrounding the Zero Age Main Sequence (ZAMS) G8.5V star HD 61005 by Chandra ACIS-S. Located only 36.4 pc distant, HD 61005 is…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
The Solar Neighborhood. LV. M Dwarf Twin Binaries -- One in Five Twin Sibling Pairs Are Mismatched in Activity and/or Rotation
Andrew A. Couperus, Todd J. Henry, Aman Kar +3
We report on a study of 36 pairs of `twin' M dwarfs in wide binaries and assess how similarly the stars behave. Stars in each twin pair have BP, RP, , , and differing b…
The Variable Radio Emission of V830 Tau and Its Putative Planet
Rachel A. Osten, Scott J. Wolk
We report on the first moderate-length time-scale observations of a young stellar object (YSO) at microwave frequencies. V830 Tau was monitored over the course of eight days with t…
The Proxima Centauri Campaign -- First Constraints On Millimeter Flare Rates from ALMA
Kiana Burton, Meredith A. MacGregor, Rachel A. Osten +6
Proxima Centauri (Cen) has been the subject of many flaring studies due to its proximity and potential to host habitable planets. The discovery of millimeter flares from this M dwa…
The NewAthena mission concept in the context of the next decade of X-ray astronomy
Mike Cruise, Matteo Guainazzi, James Aird +16
Large X-ray observatories such as Chandra and XMM-Newton have been delivering scientific breakthroughs in research fields as diverse as our Solar System, the astrophysics of stars,…
