  • 5. arXiv:1912.01610 Are Inner Disc Misalignments Common? ALMA Reveals an Isotropic Outer Disc Inclination Distribution for Young Dipper Stars Authors: M. Ansdell, E. Gaidos, C. Hedges, M. Tazzari, A. L. Kraus, M. C. Wyatt, G. M. Kennedy, J. P. Williams, A. W. Mann, I. Angelo, G. Duchene, E. E. Mamajek, J. Carpenter, T. L. Esplin, A. C. Rizzuto Abstract:Dippers are a common class of young variable star exhibiting day-long dimmings with depths of up to several tens of percent. A standard explanation is that dippers host nearly edge-on (id 70d) protoplanetary discs that allow close-in (<1 au) dust lifted slightly out of the midplane to partially occult the star. The identification of a face-on dipper disc and growing evidence of inner disc misalignments brings this scenario into question. Thus we uniformly (re)derive the inclinations of 24 dipper discs resolved with (sub-)mm interferometry from ALMA. We find that dipper disc inclinations are consistent with an isotropic distribution over id 0 to 75d, above which the occurrence rate declines (likely an observational selection effect due to optically thick disc midplanes blocking their host stars). These findings indicate that the dipper phenomenon is unrelated to the outer (>10 au) disc resolved by ALMA and that inner disc misalignments may be common during the protoplanetary phase. More than one mechanism may contribute to the dipper phenomenon, including accretion-driven warps and \broken" discs caused by inclined (sub-)stellar or planetary companions. MNRAS NA

Poggianti, P. Serra, E. Roediger, M. Gullieuszik, N. Tomicic, M. Radovich, B. Vulcani, Y. L. Jaffe', J. Fritz, D. Bettoni, M. Ramatsoku, A. Wolter Abstract: Within the GASP survey, aimed at studying the effect of the ram-pressure stripping on the star formation quenching in cluster galaxies, we analyze here ALMA observations of the jellyfish galaxy JW100. We find an unexpected large amount of molecular gas (∼2.5×1010M⊙), 30\% of which is located in the stripped gas tail out to ∼35 kp… The total amount of molecular gas, coupled with its distribution, kinematics and physical conditions are all suggesting that the molecular gas content of this galaxy is increased with respect to undisturbed galaxies of similar mass, and that this is probably due to the newly formed gas that we see in the tail coupled with an enhancement of molecular gas also within the disk.

Okamoto, Takaaki Yokoyama, Noriyuki Narukage, Taro Sakao, Kazumasa Iwai, Gregory D. Fleishman, Kazunari Shibata Abstract: We succeeded in observing two large spicules simultaneously with the Atacama Large Millimeter/submillimeter Array (ALMA), the Interface Region Imaging Spectrograph (IRIS), and the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory. One is a spicule seen in the IRIS Mg II slit-jaw images and AIA 304Å images (MgII/304A spicule). We cannot identify a hot sheath around the 100GHz spicules, but we cannot argue that a spicule without a hot sheath is common in 100GHz images. To reveal the properties of typical spicules seen in mm-wave images, we need the higher resolution enough for resolving spicules, which will be realized with the higher observing frequency and/or long baselines of ALMA.

  • 10. arXiv:1912.05605 The Role of Magnetic Fields in Protostellar Outflows and Star Formation Authors: Ralph E. Pudritz, Tom P. Ray Abstract: The role of outflows in the formation of stars and the protostellar disks that generate them is a central question in astrophysics. The recent high resolution Atacama Large Millimeter Array (ALMA) observations of disks and outflows now confirm several key aspects of these ideas, e.g. that jets rotate and originate from large regions of their underlying disks. New insights on accretion disk physics show that magneto-rotational instability (MRI) turbulence is strongly damped, leaving magnetized disk winds as the dominant mechanism for transporting disk angular momentum. This has major consequences for star formation, as well as planet formation Frontiers in Astronomy and Space Sciences, Volume 6, id.54 (2019) NA

Such measurements will usher in a new era of discoveries unraveling the formation of the first supermassive black holes based on subarcsecond-scale spectroscopy with the ALMAa), JWSTb) and the SKA. The measured mass distribution of black holes will allow forecasting of the future detection of gravitational waves from the earliest black hole mergers. ApJ? NA

Bastian Abstract: The ALMA oscillations that we detected exhibit higher amplitudes than those derived from the lower ( 1000) resolution observations at 3.5 mm by White et al. (2006). Chromospheric oscillations are, therefore, not fully resolved at the length-scale of the chromospheric network, and possibly not even at the spatial resolution of our ALMA observations. Any study of transient brightenings in the mm-domain should take into account the oscillations. A&A, Eu
  • 15. arXiv:1912.03351 Constraining the masses of planets in protoplanetary discs from the presence or absence of vortices -- Comparison with ALMA observations Authors: Paul Hallam, Sijme-Jan Paardekooper Abstract: A massive planet in a protoplanetary disc will open a gap in the disc material. A steep gap edge can be hydrodynamically unstable, which results in the formation of vortices that can act as tracers for the presence of planets in observational results. However, in a viscous disc, the potential formation of these vortices is dependent on the timescale over which the massive planet accretes mass. we can make the prediction that it is not necessary for planets to have masseson the order of one Jupiter mass to form vortices within low viscosity discs. While massive planets do indeed form these vortices, the onset of them occurs for planets that are significantly less massive, for acceptable disc viscosities and ages. We find that planets of sub-Saturn mass can form vortices down to a few Neptune masses. Whether or not planets of these low masses can explain the dark bands we see in many of these observations is a different question. MNRAS, Eu
