Multi-epoch scattered-light analysis of HD 135344B: new evidence for a spiral-driving protoplanet
J. Latour, V. Christiaens, O. Absil +17
The HD 135344B (SAO 206462) disk exhibits strong signposts of planet formation. ALMA images in the sub-mm revealed a gap-crossing dust filament whose position coincides with a twis…
The asymmetric carbon-rich chemistry of the planet-forming disk of HD 142527 triggered by late infall
Milou Temmink, Ewine F. van Dishoeck, Alice S. Booth +3
The planet-forming disk of HD 142527 is known for its azimuthally asymmetric dust trap, shadows, and spiral arms. We use new ALMA observations to investigate the molecular composit…
Disc lifetime distribution as a function of the mass of host star
Susanne Pfalzner, Furkan Dincer, Nienke van der Marel +1
The lifetime of protoplanetary discs is a critical factor for planet formation. Although the mean disc lifetime provides an estimate of the typical period available for planet form…
The role of inner disk edges in shaping ultra-short-period planet systems around late M dwarfs
S. N. Brandenberger, M. Sanchez, N. Van der Marel +2
Close-in rocky planets are the most common type of exoplanets around late M dwarfs, ranging from more temperate worlds to highly irradiated lava planets with molten surfaces, and m…
Gaps and Rings: A Near-Universal Trait of Extended Protoplanetary Discs
Quincy Bosschaart, Osmar M. Guerra-Alvarado, Nienke van der Marel +1
Substructures such as rings, gaps, and cavities are commonly observed in protoplanetary discs and are thought to play a key role in dust evolution and planet formation. However, a…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?
I. MendigutÃa, N. Huélamo, I. Jiménez-Serra +32
The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…
