I'm part of a student team working on an AI-based exoplanet transit detection pipeline using TESS light curves for a hackathon.

We're building a system that detects periodic dips, classifies them (transit, eclipsing binary, false positive, noise, blends, etc.), and estimates parameters like period, depth, and duration.

I'd love to hear from people who have worked with TESS, Kepler, exoplanet surveys, or astronomical time-series data:

• What are the biggest pain points with current transit detection pipelines?
• What types of false positives cause the most trouble?
• What information do existing tools fail to provide clearly?
• What would make candidate vetting faster or more reliable?
• Are there common mistakes student projects make when working with light curves?
• If you could add one feature to existing exoplanet detection software, what would it be?

I'm especially interested in issues around noisy data, crowded fields, blending, uncertainty estimation, explainability, and candidate ranking.

I'm my parents' first child, and I'm 20 now. My younger brother was born in 2009, so he's 16. Around 2008 and early 2009, before my brother was born, my mom had a number of miscarriages and accidental abortions due to the fact that she's A- blood type and dad is O+, and that created a lot of complications, and she was also very young (late 20s). All the miscarriages were fairly early into her pregnancy. Still, the last one right before my brother was born...she had it in the 7th month of her pregnancy, it was a baby boy, and she saw the still baby after it was taken out. Soon after that, she had my brother, and she would tell us that she saw that stillborn baby and heard him crying sometimes to the point that she'd start to lactate, and she was sure it wasn't my brother....and it happened throughout my brother's childhood.

Now that we're both older, my mom would tell us that she still sees him, and that whenever she kind of forgets about him...he shows up. And I kid you not, I'm not religious or overtly spiritual, and neither is my brother, but we've had incidents where we have felt his presence, and I've recently started seeing him around the house, too.

Mom has this theory that whenever she buys my brother stuff out of love or whenever we're happy and enjoying ourselves, he gets annoyed and feels left out, so he shows us his presence. We live right below the terrace, and sometimes in the evening we can hear somebody running and playing ball on the terrace. One time, our neighbour ligit told my mom that he saw her kid playing with a ball on the terrace, and the ball came to his terrace by mistake (the terraces are on the same level and adjacent), and he returned the ball, and my brother hasn't played on the terrace for years. A few days ago, she said she was in her room, and somebody was throwing the ball and fetching it again and again in the hallway right outside her bedroom, and it wasn't my brother (since he was sleeping).

One time, me and my brother were hanging out during summer break in the living room, and it was nighttime around 2 am or something, and we were getting along and in general having a lot of fun watching movies and laughing more than usual and out of nowhere, my earbuds case went missing seconds after I kept them on the sofa and my brother saw me keep it there too. So we got really worrid for some bizzare reason, my house is old and we have a lot of stuff so it's not unusual to lose shit like that but somehow we spent hours looking for the earbud case and the buds turning the house upside down to the point our parents got involved and when we didn't find it anywhere and we were going back to our movie in the living room....there it was plain as day, kept neatly on the sofa directly in the line of sight of the door. like you could have seen it there from any corner of the room, and we just knew who had done it.

I'm back from college this summer, and we're planning this big family trip, so naturally we're having a lot of family time, and we're buying stuff for my brother and me, and hence (due to him not recieving as much attention as us, according to mom) I've started seeing a lanky tall figure in our house wandering from the corner of my eyes, and I never get scared of it ever...neither does my mom whenever she says he shows up......

Mom says he means no harm, but sometimes when we dote on my brother a lot (and we really do ...everyone loves him a lot), he would get a little under the weather, come down with a little fever and be okay by the morning, and my mom says that it's because the child feels jealous of my brother sometimes.

So yeah, typical middle child syndrome haha, but is it normal? Like, do ghosts just grow up?
