A Large Double-ring Disk Around the Taurus M Dwarf J04124068+2438157

open access: yesThe Astrophysical Journal, 2023
Planet formation imprints signatures on the physical structures of disks. In this paper, we present high-resolution (∼50 mas, 8 au) Atacama Large Millimeter/submillimeter Array observations of 1.3 mm dust continuum and CO line emission toward the disk ...

Summary of the Second International Planetary Dunes Workshop: Planetary Analogs — Integrating Models, Remote Sensing, and Field Data, Alamosa, Colorado, USA, May 18–21, 2010 [PDF]

open access: yes, 2010
The Second International Planetary Dunes Workshop took place in Alamosa, Colorado, USA from May 18–21, 2010. The workshop brought together researchers from diverse backgrounds to foster discussion and collaboration regarding terrestrial and extra ...

Planet formation with envelope enrichment: new insights on planetary diversity [PDF]

open access: yes, 2016
Aims. We compute for the first time self-consistent models of planet growth that include the effect of envelope enrichment. The change in envelope metallicity is assumed to be the result of planetesimal disruption or icy pebble sublimation. Methods.

Let’s Sweep: The Effect of Evolving J 2 on the Resonant Structure of a Three-planet System

open access: yesThe Astrophysical Journal, 2023
Short and ultrashort period planets are peculiar types of exoplanets with periods as short as a few days or less. Although it is challenging to detect them, already several have been observed, with many additional candidates.

Planetary systems formation and the diversity of extrasolar systems [PDF]

open access: yesProceedings of the International Astronomical Union, 2010
AbstractWith the end of answer questions as, how common are planetary systems like our own in the Universe? and What is the diversity of planetary systems that we could find in the universe?, we develop a semi-analytical model for computing planetary systems formation and consider different initial conditions for generating a large sample of planetary ...

The planetary system around HD 190622 (TOI-1054)

open access: yes, 2023
Context. Giant planets are known to dominate the long-term stability of planetary systems due to their prevailing gravitational interactions, but they are also thought to play an important role in planet formation.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Implications of Differentiated Late Accretion for the Volatile Inventory of the Bulk Silicate Earth

open access: yesThe Planetary Science Journal
Earth is believed to have acquired its highly siderophile element (HSE) inventory through the late accretion of ∼0.3%–0.5% of its mass in chondrite-like materials, following the main stage of its growth. Late accretion, particularly if it originated from

Stellar Outbursts and Chondrite Composition

open access: yesThe Astrophysical Journal, 2023
The temperatures of observed protoplanetary disks are not sufficiently high to produce the accretion rate needed to form stars, nor are they sufficient to explain the volatile depletion patterns in CM, CO, and CV chondrites and terrestrial planets.
