# Possible origin of Larson's lows

## TL;DR

This paper proposes that Larson's lows, observed as constant column densities in giant molecular clouds, can be explained by a gravitational field condition that does not depend on internal cloud dynamics.

## Contribution

It introduces a new external gravitational field-based condition explaining Larson's lows, independent of internal cloud or object dynamics.

## Key findings

- Constant column densities explained by external gravity
- Condition applies to clouds, clumps, and cores
- Does not rely on internal cloud dynamics

## Abstract

It was found that approximately constant column densities of giant molecular clouds (Larson's low) can be explained as cloud existence condition in external (galactic) gravitational field. This condition can be also applied to objects (clumps and cores) embedded into the cloud and its gravitational field. Derived existence condition do not rely on any internal dynamic of a cloud and embedded objects.
