The origin of warm Jupiters (gas giant planets with periods between 10 and 200 days) is an open question in exoplanet formation and evolution. We investigate a particular migration theory in which a warm Jupiter is coupled to a perturbing companion planet that excites secular eccentricity oscillations in the warm Jupiter, leading to periodic close stellar passages that can tidally shrink and circularize its orbit. If such companions exist in warm Jupiter systems, they are likely to be massive and close-in, making them potentially detectable. We generate a set of warm Jupiter-perturber populations capable of engaging in high-eccentricity tidal migration and calculate the detectability of the perturbers through a variety of observational metrics. We show that a small percentage of these perturbers should be detectable in the Kepler light curves, but most should be detectable with precise radial velocity measurements over a 3 month baseline and Gaia astrometry. We find these results to be robust to the assumptions made for the perturber parameter distributions. If a high-precision radial velocity search for companions to warm Jupiters does not find evidence of a significant number of massive companions over a 3 month baseline, it will suggest that perturber-coupled high-eccentricity migration is not the predominant delivery method for warm Jupiters.

暖木星（周期在 10 到 200 天之间的气态巨行星）的起源是系外行星形成和演化的一个悬而未决的问题。我们研究了一种特殊的迁移理论，其中温暖的木星与一颗扰动的伴星耦合，该行星在温暖的木星中激发了长期的偏心率振荡，导致周期性的紧密恒星通道，可以潮汐式地收缩和圆化其轨道。如果这样的伴星存在于温暖的木星系统中，它们很可能是巨大的并且靠近，使它们有可能被探测到。我们生成了一组能够进行高离心率潮汐迁移的温暖木星扰动者种群，并通过各种观测指标计算扰动者的可探测性。我们表明，在开普勒光变曲线中应该可以检测到一小部分的这些扰动，但大多数应该可以通过 3 个月基线和盖亚天体测量的精确径向速度测量来检测。我们发现这些结果对扰动参数分布的假设是稳健的。如果对暖木星伴星的高精度径向速度搜索在 3 个月的基线上没有发现大量大质量伴星的证据，这将表明扰动耦合的高离心率迁移不是暖木星的主要传送方法.
