What is the protoplanetary disk

SMA and NOEMA reveal asymmetric sub-structure in the protoplanetary

IRAS 23077+6707 is a highly-inclined and newly discovered protoplanetary disk, first reported in 2024. We combine SMA baselines from the Compact, Extended and Very Extended arrays,

A young gas giant and hidden substructures in a protoplanetary disk

The detection of planets in protoplanetary disks has proven to be extremely challenging. In contrast, rings and gaps, usually attributed to planet-disk interactions, have been found in

What are these strange swirls around an infant star? ''We

The infant extrasolar planet, or " exoplanet," is creating a spiral arm pattern in the planet-forming protoplanetary disk of the 10 million-year-old star HD 135344B, also known as SAO 206462

[2506.23795] Simulation of images of protoplanetary disks

Observational manifestations of disturbances in a protoplanetary disk caused by a collision with a massive planet are studied. It is assumed that the planet moves along a parabolic trajectory

A deep Search for Ethylene Glycol and Glycolonitrile in the

Here we report Atacama Large Millimeter/sub-millimeter Array (ALMA) observations in which we tentatively detect EG and GN in the protoplanetary disk around the outbursting protostar V883

Protoplanetary Disk Survival Time-scales: A Blind Survey of

We study the protoplanetary disk lifetimes using a large sample of young stellar objects in nearby clusters. To investigate the final phase of disk dissipation, we selected 32 clusters, located

Investigating C/O Ratios in Exoplanetary Atmospheres

The resolved disk gas C/O ratios, from seven systems, generally exhibit C/O > 1 with sub-solar, or depleted, carbon content. In contrast, wide separation gas giants have atmospheric C/O ratios

The origin of the oldest solid objects in the Solar System

The solar nebula was an example of a protoplanetary disk, the structures around young stars from which all planets form. Protoplanetary disks absorb light from their host stars and also emit light.

Young Gas Giant Reveals Hidden Protoplanetary Disk

In the quest to understand the birthplaces of planets, astronomers are increasingly turning their attention to the intricate structures hidden within protoplanetary disks. These disks, rotating

Astronomers detect exoplanet shaping the protoplanetary disk

Click for original image. Astronomers using two different instruments on the Very Large Telescope (VLT) in Chile have now directly detected what they think is an exoplanet as it shapes the

Bridging the gap: consistent modeling of protoplanetary disk

A giant planet embedded in a protoplanetary disk excites spiral density waves, which steepen into shocks as they propagate away from the planet. These shocks lead to secular disk heating

New findings indicate that the origin of life started in space

The transition of a cold protostar to a young star with a protoplanetary disk is accompanied by a phase characterized by intense shockwaves and radiation that disturb gas and dust in the disk.

生命の起源は宇宙かもしれない：有機分子を若い恒星系で発見

Further observations of this protoplanetary disk at higher spectral resolution are required to resolve blended lines and to confirm these tentative detections. V883 Oriの原始惑星円盤にお

Unveiling a protoplanet candidate embedded in the HD 135344B disk

The star is located at ∼136 pc, and hosts a protoplanetary disk characterized by a 40 au cavity, multiple spiral arms detected in the optical/near-infrared, and a large-scale azimuthal

A young gas giant and hidden substructures in a protoplanetary disk

ALMA and Gaia data combine to reveal a young gas giant in the protoplanetary disk around MP Mus. Previously unseen substructures, visible only at longer wavelengths, suggest that more

New worlds in the making: Is this how our solar system was

This structure, known as a protoplanetary disk, is the very environment in which future planets form. Using JWST''s infrared capabilities and ALMA''s powerful radio imaging, scientists
