Question about Jewish memorial tradition

Is there a commonly accepted way in Judaism to memorialize a Jewish person who has recently died?

Like Catholics, for example, might go to a church and make a donation to light a memorial candle. Or they might have a mass dedicated to someone's memory.

In Buddhism, we can add someone's name to a list to be read at a Powa ceremony, which is a monthly prayer ceremony for recently departed people.

Is there any equivalent, small, token thing a layperson can do that would be similar in Judaism? Like, could I stop by a local synagogue and light a candle? I don't even know if people do that, because I've never been in a synagogue.

The reason I ask is because, as you may have heard, the actress Michelle Trachtenberg died a couple days ago from an illness and I really adored her. I wonder if there's some small way to pay my respects.
