Evaluating Star-Planet Interactions with Zeeman Doppler Imaging: Case Study in YZ Ceti
J. Sebastian Pineda, Stefano Bellotti, Jackie Villadsen +3
The recent detections of radio emission from the nearby exoplanet host, YZ Ceti, suggest that the star is possibly interacting with its rocky innermost planet. These radio emission…
Radio Signatures of Star-Planet Interactions, Exoplanets, and Space Weather
J. R. Callingham, B. J. S. Pope, R. D. Kavanagh +22
Radio detections of stellar systems provide a window onto stellar magnetic activity and the space weather conditions of extrasolar planets, information that is difficult to attain…
Coherent radio bursts from known M-dwarf planet host YZ Ceti
J. Sebastian Pineda, Jackie Villadsen
Observing magnetic star-planet interactions (SPI) offers promise for determining magnetic fields of exoplanets. Models of sub-Alfvénic SPI predict that terrestrial planets in close…
Resolved imaging of an extrasolar radiation belt around an ultracool dwarf
Melodie M. Kao, Amy J. Mioduszewski, Jackie Villadsen +1
Radiation belts are present in all large-scale Solar System planetary magnetospheres: Earth, Jupiter, Saturn, Uranus, and Neptune. These persistent equatorial zones of trapped high…
Constraining the Physical Properties of Stellar Coronal Mass Ejections with Coronal Dimming: Application to Far Ultraviolet Data of Eridani
R. O. Parke Loyd, James Mason, Meng Jin +9
Coronal mass ejections (CMEs) are a prominent contributor to solar system space weather and might have impacted the Sun's early angular momentum evolution. A signal diagnostic of C…
Differences in radio emission from similar M dwarfs in the binary system Ross 867-8
L. H. Quiroga-Nuñez, H. T. Intema, J. R. Callingham +5
Serendipitously, we have rediscovered radio emission from the binary system Ross 867 (M4.5V) and Ross 868 (M3.5V) while inspecting archival Giant Metrewave Radio Telescope (GMRT) o…
Meter- to Millimeter Emission from Cool Stellar Systems: Latest Results, Synergies Across the Spectrum, and Outlook for the Next Decade
Jan Forbrich, Peter K. G. Williams, Emily Drabek-Maunder +12
Radio observations of cool stellar systems provide unique information on their magnetic fields, high-energy processes, and chemistry. Buoyed by powerful new instruments (e.g. ALMA,…
Ultra-Wideband Detection of 22 Coherent Radio Bursts on M Dwarfs
Jackie Villadsen, Gregg Hallinan
Coherent radio bursts detected from M dwarfs have some analogy with solar radio bursts, but reach orders of magnitude higher luminosities. These events trace particle acceleration,…
Radio Emission from the Exoplanetary System Eridani
T. S. Bastian, J. Villadsen, A. Maps +2
As part of a wider search for radio emission from nearby systems known or suspected to contain extrasolar planets Eridani was observed by the Jansky Very Large Array (VLA) in t…
Using cm Observations to Constrain the Abundance of Very Small Dust Grains in Galactic Cold Cores
C. T. Tibbs, R. Paladini, K. Cleary +9
In this analysis we illustrate how the relatively new emission mechanism known as spinning dust can be used to characterize dust grains in the interstellar medium. We demonstrate t…
CARMA Observations of Galactic Cold Cores: Searching for Spinning Dust Emission
C. T. Tibbs, R. Paladini, K. Cleary +9
We present the first search for spinning dust emission from a sample of 34 Galactic cold cores, performed using the CARMA interferometer. For each of our cores we use photometric d…
Cool Stars and Space Weather
A. A. Vidotto, M. Jardine, A. C. Cameron +8
Stellar flares, winds and coronal mass ejections form the space weather. They are signatures of the magnetic activity of cool stars and, since activity varies with age, mass and ro…
First Detection of Thermal Radio Emission from Solar-Type Stars with the Karl G. Jansky Very Large Array
Jackie Villadsen, Gregg Hallinan, Stephen Bourke +2
We present the first detections of thermal radio emission from the atmospheres of solar-type stars τ Cet, η Cas A, and 40 Eri A. These stars all resemble the Sun in age and level o…
Search for High Frequency Gravitational Wave Bursts in the First Calendar Year of LIGO's Fifth Science Run
LIGO Scientific Collaboration, B. Abbott
We present an all-sky search for gravitational waves in the frequency range 1 to 6 kHz during the first calendar year of LIGO's fifth science run. This is the first untriggered LIG…
