Planet-forming disks and their environment across regions and time from the full NIR census
Antonio Garufi, Christian Ginski, Myriam Benisty +5
The evolution of planet-forming disks and the processes of planet formation influence each other, and both of them are possibly impacted by the local environment. Extensive high-re…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): V721 CrA and BN CrA have wide and structured disks in polarised IR
Gabriele Columba, Elisabetta Rigliaco, Raffaele Gratton +8
We present near-infrared scattered-light observations of the disks around two stars of the Corona Australis star-forming region, V721 CrA, and BN CrA, obtained with VLT/SPHERE, in…
The grazing angle icy protoplanetary disk PDS 453
Laurine Martinien, François Ménard, Gaspard Duchêne +12
PDS 453 is a rare highly inclined disk where the stellar photosphere is seen at grazing incidence on the disk surface. Our goal is take advantage of this geometry to constrain the…
Exploring the time variability of the Solar Wind using LOFAR pulsar data
S. C. Susarla, A. Chalumeau, C. Tiburzi +22
High-precision pulsar timing is highly dependent on precise and accurate modeling of any effects that impact the data. It was shown that commonly used Solar Wind models do not accu…
Feasibility of detecting shadows in disks induced by infall
A. Krieger, M. Kuffmeier, S. Reissl +3
Observations performed with high-resolution imaging techniques revealed the existence of shadows in circumstellar disks that can be explained by the misalignment of an inner with r…
Shock shaping? Nebular Spectroscopy of Nova V906 Carinae
É. J. Harvey, E. Aydi, L. Izzo +7
V906 Carinae was one of the best observed novae of recent times. It was a prolific dust producer and harboured shocks in the early evolving ejecta outflow. Here, we take a close lo…
Optical Variability, Rotation Period and Inclination Angle of the M9.5 dwarf BRI 0021-0214
S. Dulaimi, A. Golden, R. P. Boyle +1
We report -band photometric observations of the radio-detected M9.5 dwarf BRI 0021-0214, obtained with the Galway Ultra Fast Imager (GUFI) on the 1.8m Vatican Advanced Technolog…
ALMA Observations of the HD~110058 debris disk
Antonio S. Hales, SebastiÁn Marino, Patrick D. Sheehan +7
We present Atacama Large Millimeter Array (ALMA) observations of the young, gas-rich debris disk around HD110058 at 0.3-0.6\arcsec resolution. The disk is detected in the 0.85 and…
Coronal mass ejections and type II radio emission variability during a magnetic cycle on the solar-type star Eridani
Dúalta Ó Fionnagáin, Robert D. Kavanagh, Aline A. Vidotto +5
We simulate possible stellar coronal mass ejection (CME) scenarios over the magnetic cycle of Eridani (18 Eridani; HD 22049). We use three separate epochs from 2008, 2011, and…
A Deep Search for Five Molecules in the 49 Ceti Debris Disk
Jessica Klusmeyer, A. Meredith Hughes, Luca Matra +9
Surprisingly strong CO emission has been observed from more than a dozen debris disks around nearby main-sequence stars. The origin of this CO is unclear, in particular whether it…
Planet-induced radio emission from the coronae of M dwarfs
Robert D. Kavanagh, Aline A. Vidotto, Baptiste Klein +3
There have recently been detections of radio emission from low-mass stars, some of which are indicative of star-planet interactions. Motivated by these exciting new results, here w…
Planet-induced radio emission from the coronae of M dwarfs: the case of Prox Cen and AU Mic
Robert D. Kavanagh, Aline A. Vidotto, Baptiste Klein +3
There have recently been detections of radio emission from low-mass stars, some of which are indicative of star-planet interactions. Motivated by these exciting new results, in thi…
Two New Nova Shells associated with V4362 Sagittarii and DO Aquilae
E. J. Harvey, M. P. Redman, P. Boumis +8
A classical nova is an eruption on the surface of a white dwarf in an accreting binary system. The material ejected from the white dwarf surface generally forms an axisymmetric she…
Multi-Epoch VLBI of L Dwarf Binary 2MASS J0746+2000AB: Precise Mass Measurements and Confirmation of Radio Emission from Both Components
Qicheng Zhang, Gregg Hallinan, Walter Brisken +2
Surveys have shown that up to one tenth of all ultracool dwarfs (UCDs) are appreciable radio emitters, with their emission attributed to a combination of gyrosynchrotron radiation…
Direct measurement of stellar angular diameters by the VERITAS Cherenkov Telescopes
W. Benbow, R. Bird, A. Brill +54
The angular size of a star is a critical factor in determining its basic properties. Direct measurement of stellar angular diameters is difficult: at interstellar distances stars a…
Axions and the luminosity function of white dwarfs. The thin and thick disks, and the halo
Jordi Isern, Enrique Garcia-Berro, Santiago Torres +2
The evolution of white dwarfs is a simple gravothermal process of cooling. Since the shape of their luminosity function is sensitive to the characteristic cooling time, it is possi…
Polarimetry and Spectroscopy of the `Oxygen Flaring' DQ Herculis-like nova: V5668 Sagittarii (2015)
E. J. Harvey, M. P. Redman, M. J. Darnley +5
Classical novae are eruptions on the surface of a white dwarf in a binary system. The material ejected from the white dwarf surface generally forms an axisymmetric shell of gas and…
Multi-band photometry and spectroscopy of an all-sky sample of bright white dwarfs
R. Raddi, N. P. Gentile Fusillo, A. F. Pala +11
The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will obtain space-based uninterrupted light curves for a large sample of bright white dwarfs distributed across the e…
Modelling the structure and kinematics of the Firework nebula: The nature of the GK Persei nova shell and its jet-like feature
