Protoplanetary disks are dense regions of gas and dust rotating around a young T Tauri star. As the name suggests, protoplanetary disks are where planets form. These disks can also serve as accretion material for the young central star. In this project we aim to study about 100 protoplanetary disks in the Taurus-Auriga young star forming region. The main focus of our study is the relationships between the spectral index, fluxes at mm-wavelengths and stellar properties, as well as the correlation between the mass of the central star and the mass of dust in the protoplanetary disk. Disk masses are inferred using previous flux observations in 0.89 mm and 1.33 mm wavelengths, as well as recent observations at a wavelength of 3 mm using The Combined Array for Research in Millimeter-wave Astronomy (CARMA). This study will allow us to refine scaling laws linking disk and stellar properties, and shed light on the origin of some of the key scaling laws recently observed from the known population of exoplanets.

Why do protoplanetary disks appear not massive enough to form the known exoplanet population?

September 2018

When and how planets form in protoplanetary disks is still a topic of discussion. Exoplanet detection surveys and protoplanetary disk surveys are now providing results that allow us to have new insights. We collect the masses of confirmed exoplanets and compare their dependence with stellar mass with the same dependence for protoplanetary disk masses measured in ~1-3 Myr old star-forming regions. ... [Show full abstract] The latter are recalculated by us using the new estimates of their distances derived from Gaia DR2 parallaxes. We note that single and multiple exoplanetary systems form two different populations, probably pointing to a different formation mechanism for massive giant planets around very low mass stars. While expecting that the mass in exoplanetary systems is much lower than the measured disk masses, we instead find that exoplanetary systems masses are comparable or higher than the most massive disks. This same result is found also by converting the measured planet masses into heavy-element content (core masses for the giant planets and full masses for the super-Earth systems) and by comparing this value with the disk dust masses. Unless disk dust masses are heavily underestimated, this is a big conundrum. An extremely efficient recycling of dust particles in the disk cannot solve this conundrum. This implies that either the cores of planets have formed very rapidly (<0.1-1 Myr) and large amount of gas is expelled on the same timescales from the disk, or that disks are continuously replenished of fresh planet-forming material from the environment. These hypotheses can be tested by measuring disk masses in even younger targets and by better understanding if and how the disks are replenished by their surroundings.

Origin of the Metallicity Dependence of Exoplanet Host Stars in the Protoplanetary Disk Mass Distrib...

August 2007

The probability of a star hosting a planet that is detectable in radial velocity surveys increases Ppl(Z) oc 10^2Z, where Z is metallicity. Core accretion models reproduce this trend, since the protoplanetary disk of a high metallicity star has a high density of solids and so forms cores which accrete gas before the primordial gas disk dissipates. This paper considers the origin of the form of ... [Show full abstract] Ppl(Z). We introduce a simple model in which detectable planets form when the mass of solids in the protoplanetary disk, Ms, exceeds a critical value. In this model the form of Ppl(Z) is a direct reflection of the distribution of protoplanetary disk masses, Mg, and the observed Ppl(Z) is reproduced if P(Mg>Mg') oc 1/Mg'^2. We argue that a protoplanetary disk's sub-mm dust mass is a pristine indicator of the mass available for planet-building and find the observed sub-mm disk mass distribution is consistent with the observed Ppl(Z) if Ms>0.5M_J is required to form detectable planets. Any planet formation model which imposes a critical solid mass for planet formation would reproduce the observed Ppl(Z), and core accretion models are empirically consistent with a threshold criterion. We identify 7 protoplanetary disks which, by rigid application of this criterion, would be expected to form detectable planets. A testable prediction is that Ppl(Z) should flatten both for Z>0.5dex and as more distant and lower mass planets are discovered. Further, combining this model with one in which the evolution of a star's debris disk is also influenced by the solid mass in its protoplanetary disk, results in the prediction that debris disks detected around stars with planets should be more infrared luminous than those around stars without planets in tentative agreement with recent observations.

Astrophysics: Exoplanets hidden in the gaps

Planets develop from the disk of dust and gas that surrounds a newly formed star. Observations of gaps in the disks of four such systems have allowed us to start unravelling the processes by which planets form.
