Planet forming disk populations and their connection to the environment

Thomas J. Haworth, Giovanni Rosotti, Carlo Manara +35

Existing sub-mm observatories such as ALMA have provided statistics on the planet-forming mass reservoirs within circumstellar disks around stars in stellar clusters out to distanc…

Angular Momentum of Planet-Forming Disks: Implications for Infall Driven Misalignments

Aashish Gupta, Cristiano Longarini, L. Ilsedore Cleeves +5

Context. A significant fraction (>30%) of planet-forming disks and planetary are misaligned with respect to the rotational axis of their host stars, yet the dominant mechanism resp…

JWST-DECO: The Impact of Accretion on Mid-Infrared Observable Water in Planet-forming Disks

Jenny K. Calahan, Tarisai Dziire, Karin Öberg +13

The inner few au of a protoplanetary disk hosts the majority of observed exoplanets and is the primary planet-forming zone of the disk. The mid-IR spectra of disks, with its rich f…

A tale of three tails: A misaligned streamer and mysterious structures around [BHB2007]1

Aashish Gupta, Antonio S. Hales, L. Ilsedore Cleeves +8

Recent discoveries of streamer-like structures around protostellar sources challenge the traditional picture of isolated, axisymmetric star formation. Here, we present new ALMA obs…

Spatially correlated stellar accretion in the Lupus star forming region: Evidence for ongoing infall from the interstellar medium

Andrew J. Winter, Myriam Benisty, Carlo F. Manara +1

Growing evidence suggests that protoplanetary discs may be influenced by late stage infall from the interstellar medium (ISM). It remains unclear the degree to which infall shapes…

TIPSY: Trajectory of Infalling Particles in Streamers around Young stars. Dynamical analysis of the streamers around S CrA and HL Tau

Aashish Gupta, Anna Miotello, Jonathan P. Williams +3

Context. Elongated trails of infalling gas, often referred to as "streamers," have recently been observed around young stellar objects (YSOs) at different evolutionary stages. This…

The VLT MUSE NFM view of outflows and externally photoevaporating discs near the Orion Bar

Thomas J. Haworth, Megan Reiter, C. Robert O'Dell +10

We present VLT/MUSE Narrow Field Mode (NFM) observations of a pair of disc-bearing young stellar objects towards the Orion Bar: 203-504 and 203-506. Both of these discs are subject…

Reflections on nebulae around young stars: A systematic search for late-stage infall of material onto Class II disks

Aashish Gupta, Anna Miotello, Carlo F. Manara +10

Context. While it is generally assumed that Class II sources evolve largely in isolation from their environment, many still lie close to molecular clouds and may continue to intera…

Interplay between Young Stars and Molecular Clouds in the Ophiuchus Star-forming Complex

Aashish Gupta, Wen-Ping Chen

We present spatial and kinematic correlation between the young stellar population and the cloud clumps in the Ophiuchus star-forming region. The stellar sample consists of known yo…

Effects of magnetic field orientations in dense cores on gas kinematics in protostellar envelopes

Aashish Gupta, Hsi-Wei Yen, Patrick Koch +16

Theoretically, misalignment between the magnetic field and rotational axis in a dense core is considered to be dynamically important in the star formation process, however, extent…

The JCMT Transient Survey: Four Year Summary of Monitoring the Submillimeter Variability of Protostars

Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee +49

We present the four-year survey results of monthly submillimeter monitoring of eight nearby (pc) star-forming regions by the JCMT Transient Survey. We apply the Lomb-Scargl…

No impact of core-scale magnetic field, turbulence, or velocity gradient on sizes of protostellar disks in Orion A

Hsi-Wei Yen, Bo Zhao, Patrick M. Koch +1

We compared the sizes and fluxes of a sample of protostellar disks in Orion A measured with the ALMA 0.87 mm continuum data from the VANDAM survey with the physical properties of t…

VR CCD photometry of variable stars in globular cluster NGC 4147

Sneh Lata, A. K. Pandey, J. C. Pandey +20

We present results of a search for variable stars in a region of the globular cluster NGC 4147 based on photometric observations with 4k x 4k CCD imager mounted at the axial port o…
