Uniform Metallicity Measurements of M Dwarf Planet Hosts Support Metallicity-Dependent Sub-Neptune Formation
Emma V. Turtelboom, Steven Giacalone, Rebecca Gore +6
M dwarfs are the most common sites of planet formation in the Milky Way. Planet occurrence and composition are closely linked with the availability of metals in protoplanetary disk…
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 Lyman alpha Sky as Observed by New Horizons
G. R. Gladstone, J. M. Shull, W. R. Pryor +22
During September 2023 the Alice ultraviolet spectrograph on the New Horizons (NH) spacecraft was used to map diffuse Lyman alpha (Lya) emission over most of the sky, at a range of…
X-ray detection of astrospheres around three main-sequence stars and their mass-loss rates
K. G. Kislyakova, M. Güdel, D. Koutroumpa +3
Stellar winds of cool main sequence stars are very difficult to constrain observationally. One way to measure stellar mass loss rates is to detect soft X-ray emission from stellar…
Synergies between interstellar dust and heliospheric science with an Interstellar Probe
Veerle J. Sterken, Silvan Hunziker, Kostas Dialynas +40
We discuss the synergies between heliospheric and dust science, the open science questions, the technological endeavors and programmatic aspects that are important to maintain or d…
Mid-infrared spectra of differentiated meteorites (achondrites): Comparison with astronomical observations of dust in protoplanetary and debris disks
A. Morlok, C. Koike, K. Tomeoka +4
Mid-infrared (5 micron to 25 micron) transmission/absorption spectra of differentiated meteorites (achondrites) were measured to permit comparison with astronomical observations of…
Spectral Evidence for an Inner Carbon-Rich Circumstellar Dust Belt in the Young HD36546 A-Star System
Carey M. Lisse, Mike L. Sitko, Ray W. Russell +5
Using the NASA/IRTF SpeX & BASS spectrometers we have obtained novel 0.7 - 13 um observations of the newly imaged HD36546 debris disk system. The SpeX spectrum is most consistent w…
ALMA observations of the Corvi debris disc: inward scattering of CO-rich exocomets by a chain of 3-30 M planets?
S. Marino, M. C. Wyatt, O. Panic +10
While most of the known debris discs present cold dust at tens of AU, a few young systems exhibit hot dust analogous to the Zodiacal dust. Corvi is particularly interesting as…
The Puzzling Detection of X-rays From Pluto by Chandra
C. M. Lisse, R. L. McNutt, S. J. Wolk +17
Using Chandra ACIS-S, we have obtained imaging Xray spectrophotometry of the Pluto system in support of the New Horizons flyby on 14 July 2015. 174 ksec of observations were obtain…
Solar Wind at 33 AU: Setting Bounds on the Pluto Interaction for New Horizons
F. Bagenal, P. A. Delamere, H. A. Elliott +7
The NASA New Horizons spacecraft flies past Pluto on July 14, 2015, carrying two instruments that detect charged particles. Pluto has a tenuous, extended atmosphere that is escapin…
Evolution from protoplanetary to debris discs: The transition disc around HD 166191
G. M. Kennedy, S. J. Murphy, C. M. Lisse +12
HD 166191 has been identified by several studies as hosting a rare and extremely bright warm debris disc with an additional outer cool disc component. However, an alternative inter…
Soft coronal X-rays from β Pictoris
H. M. Günther, S. J. Wolk, J. J. Drake +3
A type stars are expected to be X-ray dark, yet weak emission has been detected from several objects in this class. We present new Chandra/HRC-I observations of the A5 V star β Pic…
