ALMA and NACO observations towards the young exoring transit system J1407 (V1400 Cen)

M. A. Kenworthy, P. D. Klaassen, M. Min +8

Our aim was to directly detect the thermal emission of the putative exoring system responsible for the complex deep transits observed in the light curve for the young Sco-Cen star…

The NANOGrav 11-year Data Set: Constraints on Planetary Masses Around 45 Millisecond Pulsars

E. A. Behrens, S. M. Ransom, D. R. Madison +27

We search for extrasolar planets around millisecond pulsars using pulsar timing data and seek to determine the minimum detectable planetary masses as a function of orbital period.…

Resolving the FU Ori System with ALMA: Interacting Twin Disks?

Sebastián Pérez, Antonio Hales, Hauyu Baobab Liu +7

FU Orionis objects are low-mass pre-main sequence stars characterized by dramatic outbursts of several magnitudes in brightness. These outbursts are linked to episodic accretion ev…

The Radial Distribution of Dust Particles in the HL Tau Disk from ALMA and VLA Observations

Carlos Carrasco-González, Anibal Sierra, Mario Flock +13

Understanding planet formation requires to discern how dust grows in protoplanetary disks. An important parameter to measure in disks is the maximum dust grain size present. This i…

From scattered-light to millimeter emission: A comprehensive view of the Gyr-old system of HD 202628 and its eccentric debris ring

Virginie Faramaz, John Krist, Karl R. Stapelfeldt +13

We present here new observations of the eccentric debris ring surrounding the Gyr-old solar-type star HD 202628: at millimeter wavelengths with ALMA, at far-infrared wavelengths wi…

First ALMA Millimeter Wavelength Maps of Jupiter, with a Multi-Wavelength Study of Convection

Imke de Pater, R. J. Sault, Chris Moeckel +15

We obtained the first maps of Jupiter at 1-3 mm wavelength with the Atacama Large Millimeter/Submillimeter Array (ALMA) on 3-5 January 2017, just days after an energetic eruption a…
