Abstract

Transition disks are natural laboratories for the study of planet formation, with inner clearings explained by the influence of accreting planets, but attempts to observe directly accretion onto protoplanets have proven unsuccessful so far; here the authors detect infrared emission from multiple companions of the LkCa 15 system and Ha emission from the innermost (LkCa 15 b), showing hot (~10,000 K) gas falling deep into the potential well of an accreting protoplanet.
