Towards using optical/NIR photometry to measure the temperature of O stars

TL;DR

This paper explores methods to utilize optical and near-infrared photometry for determining the temperatures of O stars, challenging previous assumptions and presenting preliminary results for low-extinction scenarios.

Contribution

It outlines a new approach to measure O star temperatures using optical/NIR photometry and demonstrates initial feasibility in low-extinction environments.

Findings

Preliminary results show potential for temperature measurement in low-extinction cases.

Identifies key steps to overcome past hurdles in using photometry for O star temperatures.

Suggests that optical/NIR photometry can be a viable tool for stellar temperature estimation.

Abstract

It has been traditionally stated that it is not possible to use optical/NIR photometry to measure the temperatures of O stars. In this contribution we describe the steps required to overcome the hurdles that have prevented this from happening in the past and we present our preliminary results for the low-extinction case.
