inward drift

USAGE SUMMARY

"inward drift" is correct and usable in written English. You can use it to describe a movement or tendency towards the center or inside of something. For example: "The inward drift of the crowd made it difficult to exit the venue." Alternative expressions include "internal pull," "central movement," and "inner shift."

Given the typical densities and temperatures in accretion disks, viscosity is too low to drive the inward drift.

Encyclopedia Britannica

As it approaches the star due to the P-R inward drift, its temperature rises high and it finally starts active sublimation.

Earth, Planets and Space

"Trapping the large dust particles prevents the radial inward drift and therefore allows the particles to grow to much larger sizes, up to rocks as wide as a kilometer or more".

Science Magazine

Because of the increase in ß due to ice sublimation, radiation pressure on icy dust particles prevents their inward drift due to the P-R drag, resulting in a pileup of the particles.

Earth, Planets and Space

We set a0 = 50 AU and e0 = 10-4 where a0 and e0 are the initial semimajor axis and eccentricity of dust particles starting their inward drift by the P-R drag.

Large dust particles with are collisionally ground down prior to their inward drifts.

Earth, Planets and Space

When the temperatures of the particles exceed 100 K, the ice component of the particles starts to sublimate and their inward drifts almost stop at their sublimation zones because of an increase in ß (Kobayashi et al., 2008).

Thus, Phe192 turns inward drifting below the nicotinamide ring of NADPH pushing hereafter E1 into the SUB and reaching so a similar conformation as the starting structure of C3 (1fdtB-NADPH-E1).

Plosone

As the lights come up across the city, the scene turns inward; smoke drifts beneath the lamps, people bend to twinkling glasses, an organist plays 'The Blue Danube' to the diners of Berlin.

The Guardian

Driven by the P-R drag, they drift inward until they actively sublime in the vicinity of the star.

Earth, Planets and Space

Therefore, EKB dust particles in orbit around the sun must drift inward by the P-R effect.

Expert writing Tips

Best practice

When using "inward drift" in scientific writing, ensure that you clearly define the mechanism causing the drift, such as Poynting-Robertson drag or viscosity, to provide context for your readers.

Common error

While technically correct, using "inward drift" to describe emotional or abstract concepts can sound awkward or overly technical. Opt for more common and relatable expressions like "withdrawal", "introspection", or "retreat" in such contexts.

Linguistic Context

The phrase "inward drift" primarily functions as a noun phrase. It describes a process or phenomenon involving movement toward an interior point. Ludwig examples illustrate its use in scientific contexts, particularly in astrophysics to describe the movement of dust particles.

Ludwig's WRAP-UP

The term "inward drift" refers to a directional movement towards the center of something. Ludwig AI identifies it as a noun phrase commonly used in scientific and encyclopedic contexts, to describe physical processes, as exemplified by the movement of dust particles in astrophysical systems. The usage is grammatically sound but relatively infrequent in general writing, favoring technical or academic discourse. While predominantly found in science-related sources, its metaphorical use should be approached with caution to maintain clarity and appropriateness. Overall, "inward drift" conveys a precise scientific meaning.

FAQs

What does "inward drift" mean in the context of astrophysics?

In astrophysics, "inward drift" typically refers to the gradual movement of dust particles or larger objects towards a central star due to forces like Poynting-Robertson drag or gas drag within a protoplanetary disk.

Is "inward drift" the same as "radial migration"?

While related, "inward drift" generally describes the movement of smaller particles, while "radial migration" can refer to the movement of larger protoplanets within a protoplanetary disk. The mechanisms driving each can also differ.

How can I prevent the "inward drift" of dust particles in simulations?

Researchers often invoke mechanisms like dust traps or pressure bumps to counteract "inward drift" in simulations, allowing for the accumulation of dust and the formation of planetesimals. For simulations, explore the effect of considering radiation pressure.

What are some alternative phrases for "inward drift" that are less technical?

Depending on the context, you could use terms like "inward movement", "contraction", or "centripetal motion" to describe a similar concept without the technical jargon.
