MINDS巡天利用JWST MIRI中红外观测52个原行星盘,研究类地行星形成区化学组成、气体演化及盘结构,连接盘化学与系外行星性质。

摘要:

随着开普勒卫星发现系外行星在我们的星系中普遍存在,以及行星系统结构和行星性质巨大多样性的发现,原行星盘的研究变得越来越重要。高分辨率的近红外和ALMA图像为年轻盘中正在进行的行星形成提供了强有力的证据。JWST MIRI中红外盘巡天(MINDS)旨在(1)研究恒星光谱类型中类地行星形成区的化学组成,(2)追踪气体演化进入盘消散阶段,以及(3)研究中红外热辐射下的原行星盘和碎片盘的结构。因此,MINDS巡天将在盘的化学组成与系外行星性质之间架起一座桥梁。该巡天包含52个目标(Herbig Ae星、T Tauri星、极低质量恒星和年轻碎片盘)。我们主要获取MIRI/MRS高信噪比(约100-500)光谱,覆盖4.9至27.9微米的完整波长范围。对于少数选定目标,我们还获取NIRSpec IFU高分辨率光谱(2.87-5.27微米)。我们将通过微米级尘埃的热辐射寻找行星形成的标志——这些信息与近红外散射光来自小尘埃颗粒和亚毫米波段的来自大尘埃的辐射互补。我们还将研究三个关键系统中盘的空间结构,这些系统已显示出行星形成的标志:TW Hya和HD 169142分别使用MIRI日冕仪在15.5微米和10.65微米处观测,PDS70使用NIRCam在1.87微米窄带和4.8微米中带滤光片成像。

英文摘要:

The study of protoplanetary disks has become increasingly important with the Kepler satellite finding that exoplanets are ubiquitous around stars in our galaxy and the discovery of enormous diversity in planetary system architectures and planet properties. High-resolution near-IR and ALMA images show strong evidence for ongoing planet formation in young disks. The JWST MIRI mid-INfrared Disk Survey (MINDS) aims to (1) investigate the chemical inventory in the terrestrial planet-forming zone across stellar spectral type, (2) follow the gas evolution into the disk dispersal stage, and (3) study the structure of protoplanetary and debris disks in the thermal mid-IR. The MINDS survey will thus build a bridge between the chemical inventory of disks and the properties of exoplanets. The survey comprises 52 targets (Herbig Ae stars, T Tauri stars, very low-mass stars and young debris disks). We primarily obtain MIRI/MRS spectra with high S/N (~100-500) covering the complete wavelength range from 4.9 to 27.9 μm. For a handful of selected targets we also obtain NIRSpec IFU high resolution spectroscopy (2.87-5.27 μm). We will search for signposts of planet formation in thermal emission of micron-sized dust - information complementary to near-IR scattered light emission from small dust grains and emission from large dust in the submillimeter wavelength domain. We will also study the spatial structure of disks in three key systems that have shown signposts for planet formation, TW Hya and HD 169142 using the MIRI coronagraph at 15.5 μm and 10.65 μm respectively and PDS70 using NIRCam imaging in the 1.87 μm narrow and the 4.8 μm medium band filter. ...
