AI 中文摘要
我们推出一款用户友好型网页应用，允许用户从TESS全帧图像中提取、可视化并与TESS光变曲线（LCs）进行交互，该服务适用于TIC数据库中识别的任意恒星，或通过恒星坐标指定的恒星。TESSExtractor采用以目标天体为中心的圆形孔径进行测光，并使用天环带进行背景扣除；该应用还利用TESS提供的共趋势基向量校正测光，以消除可能的系统效应。研究采用Lomb-Scargle周期图从光变曲线中获取周期。TESSExtractor的网站提供直观界面，兼具科研与教育用途，公开可访问。该工具简化了TESS光变曲线的分析，为各类科学目标（如恒星自转、活动、暂现源探测、星震学，或行星凌星、恒星伴星的探测等）下提取与分析TESS数据的研究者提供重要见解。TESS助力加深人类对时域天体物理学的理解，TESSExtractor则为科学利用TESS数据提供了便捷直观的网页界面。我们证实，TESSExtractor生成的光变曲线质量足以支撑定量与形态学时域研究。
英文摘要
We present a user-friendly web application that allows users to extract, visualise, and interact with TESS light-curves (LCs) from full-frame images. The service works for any star identified in the TIC database or using stellar coordinates. TESSExtractor performs photometry using a circular aperture centred on the object of interest, with a sky annulus for background subtraction. The application also uses cotrending basis vectors provided by TESS to correct photometry for possible systematic effects. The Lomb-Scargle Periodogram is used to obtain periods from the LC. The TESSExtractor's website offers an intuitive interface for scientific and educational purposes and is publicly available at https://www.tessextractor.app. This tool simplifies the analysis of TESS LCs and provides valuable insight for researchers seeking to extract and analyse TESS data for a variety of scientific goals (e.g., stellar rotation, activity, transient detection, asteroseismology, or simply detection of planetary transits or stellar companions, among others). TESS provides insights into our understanding of time-domain astrophysics, and TESSExtractor provides an accessible and intuitive web interface for scientific exploitation of TESS data. We demonstrate that TESSExtractor produces LCs of sufficient quality for both quantitative and morphological time-domain studies.
